I wanted to update you all that I have not abandoned you all. It's just Christmas night I got VERY VERY ill with a hospital-grade superflu I acquired a few days prior while visiting my father when he was in the hospital. I had a very high 104.5F fever that night and was pretty debilitated for days after as such serious flus tend to do. It has taken me a while to get better and get back into the swing of things. I see that discussion has been fairly constructive given the scope of a public forum so I am positive about the prospects of eventually resolving this. Indeed, I am very positive about the prospects the 2020s are offering in general. Oh I know it will be a lot of hard work and struggle but anything worthwhile always is. ANYWAY, this post is technically irrelevant so I will leave it there. Just wanted to let you know that I haven't just abandoned this or all of you as may or may not have been suggested. I look forward to constructive monitoring

I use extension «User Agent Switcher» (by Chris Pederick, https://chrispederick.com/) to quickly change UserAgent. Unfortunately, the author has not updated this extension since 2011. Last official build - 0.7.3.1 (January 4th, 2011). The build 0.7.3.1 can not spoofed property «navigator.oscpu» and real version OS is visible. I changed the build 0.7.3.1 - added a property "navigator.oscpu" for spoofing. Checked in FF 52.9.0, Serpent and MyPal. My unofficial build 0.7.3.2 in the attachment and here - https://www.upload.ee/files/10968463/user_agent_switcher-0.7.3.2-unofficial-fx_sm.xpi.html user_agent_switcher-0.7.3.2-unofficial-fx+sm.xpi

As Windows 8/8.1 never caught on in the corporate world, I expect history to repeat itself. Not only in the case of Chrome, but I'm sure several other applications will drop support for Windows 7 and 8.x simultaneously, as with what happened back in the early-to-mid 2010s with Windows XP and Vista. There may be an outlier or two that does officially support 8.x but not 7 (there were actually several, where applications supported Vista+ but not XP), or there may be some programs that, despite officially "requiring" Windows 10, may continue to run on Windows 8.x anyway, but I wouldn't count on it. Someone correct me if I'm wrong, but if I had to guess, Windows 8.x is more related to Windows 7 when it comes to APIs (at least on the desktop/win32 side of things, not UWP) so I'd say if something doesn't work with 7, it won't work with 8.x either unless it officially supports it. I would argue that Chrome support for Windows Vista was dropped even further back than that, with the release of Chrome 41 in March 2015, when Vista users were royally screwed over. This was the first version of Chromium/Chrome to lack a Windows Vista-exclusive build, when Vista users were simply thrown onto the XP version which caused a lot of Vista-exclusive APIs and features, most notably Windows Aero, to no longer be utilized. This was done apparently "due to lack of user feedback from Vista users", but I still believe they did it to "throw the baby out with the bathwater" so they wouldn't have to worry about supporting anything older than Windows 7. Still makes me furious to think about to this day. As Vista is much more similar to Win7, delivering its version of Chrome to Vista users would have made much more sense and would have made everyone much happier, but alas...

I was back in northern Italy and I stumbled on this: Apparently, someone tried to remotely reboot this train ticket machine, but it got stuck on "You can now turn off your computer" because of missing ACPI drivers, which is weird considering that it's an embedded machine. Anyway, this just shows that in 2020 Windows XP is still very much alive all over the world.

Since Mr. Tobin's Borealis is itself derived from SeaMonkey, roytam1's derivative might perhaps be branded MonkeySeaMonkeyDo.

Hi, just to avoid a little misunderstanding: Yes I mentioned to like Lunaris, sounds nice and hints to Moon etc. But Draconis is the exact opposite, couldn't stand to daily use a browser sounding so cruel (draconic/ian), but luckily don't need to anyway ;-)

Windows XP and POSReady 2009 are 95% identical, the only differences are in the set of standard programs (for example, in POSReady there are no games, but there are programs for Embedded capabilities). The kernel of the system, components, drivers, all this is completely the same.

A peach? Hmm, not so bad at all... Much more my taste as snakes 8-) A peach... and.... cherries... Shall we do fruits? His changelogs are full with "cherry-picking", very fitting :D

Oh God... 1 GB with Win10 means no RAM whatsoever is left for the user to open up programs and so on: everything is put on the paging files and moved back and forth from the HDD to the RAM and vice versa. Not only it's gonna reduce the life of the Hard Drive, but it's also going to be extremely slow...

@VL Sorry but I keep thinking it's your own decision to waste that time, after first experiences. I know it's not quite easy to suppress an urge to reply anyway. I do highly appreciate all the help you give, it really is extremely useful, also for later readers. What I just personally find rather sad in todays world is that real trolls, who only post to disrupt and attack and offend, and enjoy it, never get any trouble, quite the opposite, instead it's usually kind people who never do any harm who get hunted for no crimes at all.

@Mathwiz : Hope you're doing fine in the new year ; when you first posted this some days ago, I was genuinely puzzled, but since I was occupied with other matters, both in digital (!) and real life , I left it aside for future investigation; my contribution to the subject at hand was simply which basically links to the old Bugzilla bug #967977 Today I had some extra time and decided to search the official UXP GitHub repo/issue tracker, to find proof which substantiates the report that: (them in that context refers to TLS Session Tickets/TLS cache); I've searched specifically for code that sets the hidden pref security.ssl.disable_session_identifiers to true, but my search was, alas, fruitless... I then browsed @roytam1 's forked UXP repo, both branches (master+custom), for similar code signs, but to no avail, again ... So, by simply going with public source code, I found no clues that the default behaviour in either (official) PM28 and/or (forked) NM28 is to disable TLS session tickets, as you suggested... But you are not to blame yourself , I have myself in the past "slipped" in a similar fashion... ; the blame lies on the OP, for causing undue confusion over a "supposedly" new-found issue, most likely self-inflicted: ... was the post that started all this ; as part of my investigation, I have downloaded said NM28 build (BuildID=20200104010047), as well as the one after it (BuildID=20200110230556) and guess what one finds by visiting https://www.howsmyssl.com in a brand new/fresh (browser) profile: and So, nothing has changed in NM28 with regard to TLS Session Tickets, they are enabled by default (which yields the green "Good" button in that test page) ... Once more, it was simply @msfntor 's troll-ish behaviour in posting unchecked/unverified untruths, which ended up wasting people's time...

No. The problem lies in the fact that noone has a clear idea of what testing or validation is, and programs are written, more often than not by lazy/sloppy programmers, but also by good, attentive and knowledgeable ones, that do not know anything about the actual processes involved (because there are always one or more middlemen involved, so that the actual final customer, the guy/gal that actually has to use the program or maintain/service the machine never communicates directly with them and viceversa). The program is anyway always late and what is released is invariably - in the best cases - an early beta, and all the bug finding and reporting is demandated to the client, that normally has no idea on how this is done (remember, the client is the one that pays the money to buy something that he has not the capabilities to develop in-house). It is peculiar (and I believe rather unique to the (largely bad) software industry to provide "solutions" that are not working (or not fully working) AND to put the blame on the clients (you know, again, the ones that actully pay for the service) OR asking them to lose hours, days, weeks into troubleshooting the crap they produced. More loosely it is called "professionalism" and most of the software industry has no idea of what it is. Imagine you go to your barber and he after taking your (good) money for a haircut gives you a pair of scissors telling you "If in the next few days you see some tuft sticking out of your head just cut it off" or - which is what the large software companies do - "You also owe me 100 bucks for a week of assistance, if you see some tuft sticking out you just drive here and I will cut it", or - alternatively - "In case you notice some hairs sticking out call me an I will be happy for a mere 200 bucks to come to your house and cut them level with the rest". Then you go to get your car from the mechanic and he tells you "Ok, I changed the tires, I am pretty sure that I did tighten the nuts properly, should you lose a wheel, don't worry, it is covered by warranty, you just bring me back the old wheel and I will fit a new tire on it for free". Then you go to a restaurant and the cook tells you "The food I prepare is fine, should you by any chance get poisoned i will reimburse you part of the bill". jaclaz

The final version will be released on January 14, in 7 and 8.1 it will be installed as a normal browser, and in 10 it will replace the system EDGE without the possibility of removal. The ability to run it in XP is the same as vanilla chrome, i.e. null.

Jody Thornton said: > I can't believe I'm going to say this, but I have a hard time believing that the user base remaining is that low. I believe it's mainly due to fake UserAgent strings. When websites start boycotting certain old systems or browser versions, first with nags and then kicking visitors out completely, when more and more sites are getting hostile, users are just forced to fake their browser strings. And miraculously most websites start working again, fully or almost, without any "support" necessary... Same effect as for Win98 in the past. And a second dilemma, when statistics drop below a certain low level, it becomes an increasing privacy/fingerprinting risk to belong to such a tiny minority.

old good TCPMP for Windows may work as well, it even work on NT 3.51.

POSReady updates have closed many vulnerabilities and added many new features, so it is advisable to install all of them.

Presumably not, but I do have Excel 2010 installed I'll try downloading it and installing it manually, I guess

That's the saddest slope I've ever looked at... That's right. I'm one of those people faking my user agent, however I only bump the number of the version of Chrome to match the very latest release and many websites are happy with that. Most of the times there's no need to also change the OS. The last thing I want is to increase the share number of the bloody Windows 10! Besides I like the idea of people spitting out coffee when they check their website stats and they see "Windows XP x86 - Chrome 80".

it was reported in upstream: https://forum.palemoon.org/viewtopic.php?f=3&t=23566

Try to use the UOC Patch and Enforcer. See if it makes a difference.

I always turn off "experimental filters" and no problems.

You may have overlooked the word "only" in Jody's question., which is not actually answered in that article.

Now does this mean that the new MS Edge will only support Windows 7 for the same period of time?

I would also like to see a picture of the moron rectius "person" that upgraded a 1 GB PC to windows 10, but unfortunately there are all the Privacy Laws, GDPR and what not, so that is not possible . jaclaz

I don't mean to grave-dig, but I've noticed this topic on MSFN tends to come up first in a google search. After over a decade, I finally found a Windows 98/ME compatible driver. https://retrosystemsrevival.blogspot.com/2019/06/intel-945gm-display-driver-for-windows.html To install this driver: 1) You must install LoneCrusader's unofficial Windows 9x chipset drivers. Be sure to apply to EVERY applicable missing driver (every hard drive shown). Failing to do so will result in this driver not working!! 2) Install DirectX 9. This is REQUIRED as shown in Windows 2000 or later. 3) Go to device manager and manually install INF file from Windows 2000 folder. This driver does not install through the installer because of an artificial OS block! 4) Restart your computer and enjoy!! This driver was tested on a Thinkpad R60! Sadly, I have yet to find a working SoundMax HD Integrated Audio driver for Windows 9x...same goes with the wireless card!

... According to: https://nakedsecurity.sophos.com/2020/01/09/browser-zero-day-update-your-firefox-right-now/ disabling IonMonkey JIT by setting: javascript.options.ion;false will get you covered , but with a (slight) performance penalty, of course... The linked article mentions that mitigation only in relation to the Tor Browser (and until the time it gets updated, which it did), but that same "about:config" pref is apparently present in FxESR 52.9.x, which, as we all know, won't be patched...

Not weird at all. It is one problem with using Embedded OSes, you don't know what you are missing until you run into a problem. The issue being is that most software developers (or ISVs) write their software for, and test it on, retail Windows XP. When the time come to move to an Embedded product, presuming they are not opting for an Enterprise SKU, the OS is built from the ground up. The client sends a list of requirements, and a demo installation is created and sent to the client.* The client tests their software with their hardware and makes reports back any problems. The Embedded Partner then adjusts the OS and the ISV will retest until they are satisfied. Then the unit gets approved and is put on site somewhere. The problem lies with situations where the client doesn't test for all situations that their product would be involved in, or they may not communicate a need properly. Then on the other side, the documentation of what package does what is not detailed enough when building an OS. So these things do end up happening. There are also situations where an expected OS component you would think is enabled by default ends up not. One example I can think is that even if you install the USB package for Windows 8.1 Industry Pro, USB (bi-directional) 2.0 or 3.0 doesn't actually work. One client I build this OS for got all the way past testing phase and had units on site when it was determined their machines did not have fully functional USB. The issue was discovered when they tried to do firmware updates using USB keys. There have been other situations where expected low-level functions are missing, and since they are not documented properly, can take a while to figure out. Another I recall is an OS (I forget which Embedded SKU it was) didn't support the function of RS232 (Serial Port) but did install the drivers for the device. *This example follows the ISV/Embedded Partner model and not the in-house model.

ADIXctlLevel=1; I am not sure about this setting and its understanding. I got this setting from Win2K. Application Data Interface transfer control logic level. Programs invoked by XCTL commands run one at a time as part of a single task but is multi tasking. When a user selects a menu item the program should issue an XCTL command to transfer control directly to that program. The first program which receives the control directly is at highest logical level which is Level 1. More investigation is required with multi tasking and different tasking methods. This setting may not make any noticeable difference. ConservativeSwapFileUsage=0 If conservative swap file usage is employed then the maximum RAM memory usage is used before switching to the HDD swap file. This caused problems with certain programing and so I did not set it to 1 anymore. [MathCoprocessor] FPUFlags=1 This setting came with Borland C. This was originally set to 0 but I thought that 1 made a performance improvement. Most of the following has been quoted from https://xem.github.io/minix86/manual/intel-x86-and-64-manual-vol1/o_7281d5ea06a5b67a-197.html x87 FPU Floating-Point Exception Mask Bits The exception-flag mask bits (bits 0 through 5 of the x87 FPU control word) mask the 6 floating-point exception flags in the x87 FPU status word. When one of these mask bits is set, its corresponding x87 FPU floating-point exception is blocked from being generated. Zero is Invalid Operation, 1 is Denormal Operand. These are the only settings that can be used as a BSOD I think will occur with higher settings, see the above link for what other settings are. It is the Floating point value rounding and how it is achieved that is what is at stake here. See https://en.wikipedia.org/wiki/Denormal_number The following is a quote from this link. "Some systems handle denormal values in hardware, in the same way as normal values. Others leave the handling of denormal values to system software, only handling normal values and zero in hardware. Handling denormal values in software always leads to a significant decrease in performance. When denormal values are entirely computed in hardware, implementation techniques exist to allow their processing at speeds comparable to normal numbers;[3] however, the speed of computation is significantly reduced on many modern processors; in extreme cases, instructions involving denormal operands may run as much as 100 times slower.[4][5]"

I cannot say I've ever run into this problem you speak of. I've even installed XomPie on server 03, didnt happen there.

@Werewolf Thank you so much for the HUGE list of additions! Finally got around to adding them all. Glad to see you around again. I have you to thank for my list gaining popularity in early/mid 2017 thanks to the plethora of additions you provided then. Thanks again! In addition to what Werewolf posted, I have added another piece of software called Ripcord to "Instant Messaging" section, after discovering it in a thread over at the XP forum here. What makes this software unique is that it provides a fully functional Discord client for Windows Vista users, which I much prefer to using the Web version: As you can see, this is based on QT, rather than the infamous Electron (which is like a cancer contributing to the sharp decline in software support for Windows XP/Vista since 2015 ) which allows it to work flawlessly on Windows Vista. Voice Chatting also works great, for those wondering. I can't seem to find any system requirements listed anywhere, but since it does not work on Windows XP (giving a "not a valid win32 application" error message, indicating the software was built targeting Windows NT 6.0 as the minimum) I will assume that it officially supports Windows Vista or later. Also, Telegram Desktop 1.8.15 has been listed as the last version for Windows XP and Vista (1.9.0/1.9.1, both pre-releases, do not work due to missing DLL functions; the developer has stated here that it will not be fixed).

@Cixert : The "Preferences" (no file extension there!) file is the one that stores your custom browser preferences (modified from their original default values) and, as posted, should be found within your "Profile" folder, usually under ".\User Data\Default" First, BACK UP that file to a secure location in your disk, before you attempt messing with it manually; any such attempt should be made with the browser exited! The file itself is in a human-readable "pretty-printed" JSON format; open with a proper text/code editor; search for string "accept_languages" It should be there (with, I suspect, zh-CN as the first/default choice in the official Chinese version of 360EEv11); if this JSON block isn't there in your case (but it should be in an already used profile where the user has selected the English language pack), then you should create yourself a nested JSON block for it... I opted to display pages in the Greek language, if available, first - for example, the Google Web Store[GWS], so my manually modified setting inside the "Preferences" file looks like below: "intl": { "accept_languages": "el-GR,el,en-US,en" }, That code means that whenever the page hasn't got a Greek version available, the browser will fallback to displaying the American-English localization of it, and so on (if you add additional locales in that line) ... (Save the modified file while the browser is closed, then launch the browser anew and check for the effect of your new "custom" preference!) Hope I've helped

The patched version of EE 360 browser has preference for displaying sites in Russian. How do I force it to English? Relevant items in Settings page seem to be missing. Edit: found solution. 360Chrome\Chrome\User Data\Default\Preferences With text editor, look for "accept_languages" Flip language order like: "accept_languages": "en-US,en,ru-RU,ru" Clear cookies or start with new Portable if sites are still RU.

I've just finished re-testing latest Firefox (Nightly) ESR 45.9.18 (2019-12-07) (32-bit) and in my Vista SP2 x86 laptop: 1. The browser's WMF implementation is broken ; no matter the value of media.wmf.enabled (default is true), the browser can't access native OS patented decoders; hence, tests like https://demos.flowplayer.com/videotest/mp4.html fail on a stock profile/installation! So, despite being on Vista SP2 (fully updated codec wise), I still have to add to the browser a functioning h264+aac decoder, very much like in Windows XP 2. The two available choices for a h264+aac decoder to be added to roytam1's FxESR45 fork are: a. The Adobe Primetime CDM ; at least here on Vista, the browser fetched and installed the (first) older version 15 of the CDM; I double-checked the CDM is enabled in about:addons => plugins and that its decoder is also active, "media.gmp.decoder.enabled;true" b. If you don't have/don't want to install the APCDM, then you download and "install" (this is a local "portable" installation) the (linked on first page) LAV Filters DLLs (to be placed adjacent to firefox.exe) I have tried both methods (but not when both decoders are present and enabled ; you can disable APCDM from within about:addons (and its decoder from within about:config) but, AFAIK, you can't disable LAV Filters in any way other than removing them from main appDir); both methods yield a working h264+aac decoder (various HTML5 MP4 tests succeed). As for Twitter in particular, the sample video page does load successfully https://twitter.com/i/status/1160137655524270080 without messing with the User-Agent, but, probably due to older JS+CSS support in FxESR45, the PLAY button does not stay visible on-top of the embedded HTML5 player (I have "media.autoplay.enabled;false" so that video clips don't autostart ; however, if you click on the clip area, the video playback will successfully start (with an MP4 decoder properly "installed" beforehand): So again @msfntor, your inability to achieve Twitter clips playback is due to something particular to your FxESR45 profile and your OS version (XP SP2 x86); check if Twitter plays in a default FxESR45 profile with ONE of the two MP4 decoders properly installed - it is uncertain yet whether APCDM (v15/17) and the LAV DLLs work as expected under XP SP2 32-bit; it may be only one of these solutions works for you! If you can successfully install one of the two solutions, then, as instructed, check in an otherwise untouched browser profile; if Twitter plays (with a DIRECT connection, don't use Proxies/VPNs), then it's something else you've changed! Twitter normally send HLS streams, these require a working Media Source Extensions (MSE) implementation in the browser you're testing with; in FxESR45 verify: media.mp4.enabled;true media.mediasource.enabled;true media.mediasource.mp4.enabled;true And I repeat: Less Is More; I only use uB0-legacy in most browsers, I don't feel I need more "protection"... Me humbly thinks uMatrix causes you more trouble than it's worth ... And one last comment, if you will: @roytam1 , God bless him always , provides a wide selection of browser forks, to cater to various user cases; but you don't have to have (and test) all these browsers on your system! Stick to the one better working/most suitable for your browsing habits/needs (I personally alternate between NM28/UXP and St52/UXP, occasionally using St55/Moebius, since my CPU does support SSE2).

Yes, Windows XP here, so what do you think about WMF items in my about:config (media.wmf.enabled in default, true this one, others in false)?...Set it to false? or reset it? No problem? Thank you @VistaLover for your detailled, always interesting comments!

I will use my PC with XP even after the end of POSReady support. I trust my Security Setup.

I am using latest ESET nod32 for some time . It is so lightweight. I am really impressed. I never recommend any AV but I can't do same for this one .
