Those builds are originally for my private use and they are released because of my goodwill that I think they may help others. This bug doesn't affect me and so I don't have big intention on hunting and fixing it. If you want this to be fixed you at least need to find when the problem started to occur. and last but not least, stop gaslighting.

FFmpeg update. XP: static shared libfdk-aac VISTAx86: static shared libfdk-aac

This thread is about @roytam1's browsers targeting legacy OSes. And that means even browsers under Windows 7 and Windows 8 as they are also legacy in the meanwhile. But I think @Zorba the Geek is looking for a solution under Windows XP.

I COMPLETELY agree @VistaLover. By the way, you really did a complete job in your above assessment. I'm also grateful to what @K4sum1 gave us. But I also need to look after my needs. While I hate that we have a Google-fied web, I've stopped worrying about the implications of all of the privacy issues we face. It's not that I disagree with the level of concern, but it's that we REALLY can do nothing about it. I need to perform online banking, watch and help produce videos on YouTube, use WebRTC to voice traffic reports, and take part in Zoom meetings, Google Meet and Teams Meetings, and apply for work; all which basically NECESSITATES providing a good chunk of personal information to proceed. I don't agree with the corporate tactics, but I must continue to function. It was indeed K4Sum1's project, as Pale Moon was Moonchild's. What I feel these visionary types (who admittedly deserve a lot of credit for their work), fail to realize is that those that make up their user base are CONSUMERS or CUSTOMERS. Now Moonchild and his "moonie minions" VEHEMENTLY disagree with that. But customers are not just defined as those providing monetary exchange to a company or corporation for a product. They can be those who provide voluntary stake to a company, or mission. So in this way, those who co-develop alongside Moonchild, those who provide add-ons, those who beta test, and YES even those who simply (and regularly) USE Pale Moon, are indeed customers and stakeholders. When someone creates a project, and it attracts users to the resulting product, such as in K4Sum1's r3dFox, expectations begin to be developed. No matter if these expectations are right or wrong for the userbase to behold, they are real, and the developer needs to contend with them. Those are simply the facts. K4Sum1 provided a way for me to use Windows 8 on an extended basis, and you become reliant on that. When K4Sum1 understandably says, "I'm just not feeling it", it doesn't incite a favourable response among the userbase. Fair? Perhaps not, but it's a very real sentiment. @K4sum1, I genuinely hope you are OK.

I didn't realise there were so many still using SP2 (why?). I will consider building the next version with PyInstaller 5.13.2 again. But do note, that in the future that may not be possible any more, due to the changes they make. Consider upgrading to SP3. In the meantime, here is a build that should work on SP2. @davidz, Do you really mean you're on SP3? Because in my SP3 machine (VM), 2025.12.06.064237 works fine: [debug] Command-line config: ['-v'] [debug] User config "C:\Documents and Settings\Nico\Application Data\yt-dlp\config.txt": ['--rm-cache-dir', '--console-title', '--add-metadata', '--embed-thumbnail', '--convert-thumbnails', 'jpg', '--js-runtimes', 'quickjs', '--ppa', 'ffmpeg:-metadata synopsis=""', '-o', '~/Bureaublad/%(title)s.%(ext)s', '-S', 'res:1080,vcodec:avc,acodec:m4a', '--sponsorblock-remove', 'all', '-N', '6'] [debug] Encodings: locale cp1252, fs utf-8, pref cp1252, out cp1252 (No VT), error cp1252 (No VT), screen cp1252 (No VT) [debug] yt-dlp version nicolaasjan/yt-dlp@2025.12.06.064237 (winXP_x86_exe*) [debug] Python 3.11.4 (CPython x86 32bit) - Windows-XP-5.1.2600-SP3 (OpenSSL 3.5.2 5 Aug 2025) [debug] exe versions: ffmpeg N-121824-g775b102182-WINXP (fdk,setts), ffprobe N-121824-g775b102182-WINXP, phantomjs 1.9.8 [debug] Optional libraries: Cryptodome-3.23.0, brotli-1.2.0, certifi-2025.11.12, mutagen-1.47.0, requests-2.32.5, sqlite3-3.50.4, urllib3-2.6.0, websockets-15.0.1, yt_dlp_ejs-0.3.1 [debug] JS runtimes: quickjs-2025-09-13 [debug] Proxy map: {} [debug] Request Handlers: urllib, requests, websockets [debug] Plugin directories: none [debug] Loaded 1853 extractors Removing cache dir C:\Documents and Settings\Nico/.cache\yt-dlp ..

If you ***REALLY*** want your video playback looked into, it's kind of ON YOU to do some LEGWORK in NARROWING IT DOWN. *Shoot the messenger* all you want. But that really is the reality of the situation. We (you!) need to tell roytam "playback WORKS in this month-day-year release, but it is BROKEN one week later with the month-day+7-year release".

Notice: seems need some more time on ironing out front-end (win11) related revs from upstream which hopefully can be done in xmas, but UXP related changes are in and hopefully new build (without those front-end changes) will be available this week.

this site uses await, which is filed in https://repo.palemoon.org/MoonchildProductions/UXP/issues/2229

Totally understandable; sincere condolences for the loss of life of so many of your compatriots ...

The problem with posting new topics should now be fixed.

Thanks as always to a thoughtful writeup. I'll add my own slight additions. I myself have not "installed" any software for the better part of two decades, I do as much as possible via PORTABLE applications. PortableApps.com popularized the use of portable software. They began in 2006. WinPenPack has actually been around for slightly longer (by mere months, not years). You go even further back (by years) when you include those of us with familiarity to UNIX. With regard to associations with protocols/files/applications, portable software isn't really about not having these associations, but rather having exact and precise finite control of these associations. This PRECISE CONTROL is really only limited by the user's own intentions/imagination. You really can have this PRECISE CONTROL be as simple or as complex as your heart desires. Your "host system" does NOT have to have *ANY* 'default browser' associations, no txt file associations, no ini associations, no pdf associations, no mkv/avi/mp4 associations. NO ASSOCIATIONS of any kind. But you can mix-and-match to your heart's content. Associate 'browser' protocols (http/https/ftp, for example) to all use Firefox *ONLY IF* PortableApps PLATFORM is running in the systray. But roll those ftp protocols over to something like CuteFTP *ONLY* if LiberKey is running in the systray. Split your media file associations so that audio files divert to VLC Player, mkv files divert to PotPlayer, mp4 files divert to Media Player Classic, and avi files divert to TEncoder Video Converter. "Portable" really can be as simple or as complex as you "need it to be".

IIRC, the "nonsetup" zip versions were created for "special" cases (namely WinXP machines without all SPs and/or partially updated), where the provided ".exe" installers wouldn't run; FTR, the first "*_nonsetup.zip" release asset saw the light of day with the 124-r4 release: https://github.com/win32ss/supermium/releases/tag/v126-r4 As posted by NHTPG, these are NOT "portable" packages; Supermium "portable" packages were once offered as part of a paid for Patreon subscription: https://www.patreon.com/posts/supermium-122-r2-103469536 If you don't mind the registry being written to, a simplistic "portable" approach would be to write a "Sm-Portable.cmd" batch file: place it adjacent to Sm's main executable (chrome.exe) and ALWAYS launch Sm via that (you can alternatively create a Windows shortcut with the same cmdline args) ; be mindful: "portable" apps are NOT meant to be associated with other protocols/files/applications etc. ...

I assume that @Zorba the Geek is looking for a client targeting Windows XP. However, your recommended email client Betterbird requires at least Windows 7 64bit.

Yes. Install it from the Mozilla Add-ons page! For example the British English Dictionary (the only real English ): https://addons.mozilla.org/en-US/firefox/addon/british-english-dictionary-2/ Here is a screenshot taken from my Mypal 74.1.4 installation:

Understood, but @Tripredacus was consulted on this occasion, and agreed that no further action was needed in this case. That will not always be the case of course.

Yes, I filed a complaint this morning (it was already "deleted"). Instead it's maybe better to use a PrivateBin instance. https://github.com/PrivateBin/PrivateBin

Once again, learning a lot! I don't use R3dFox to watch DRM comment, so I didn't even realize R3dfox had disabled DRM. As you say, shades of Pale Moon. All the niche browsers combined aren't going to force YouTube et al. to abandon it! And I agree that the correct way to deal with the issue is to leave the DRM supporting code in the browser, and just disable it with a pref, which can then be re-enabled by the user if desired. Finally, I do consider VMP evil, and understand that niche browsers like R3dFox will never support VMP. But as long as there are sites that impose DRM but don't require VMP, we should still be allowed to access those sites. All that said, though, I still appreciate having R3dFox on my "ancient" Win 7 PC and will keep using it for the ever-increasing number of Web sites that flummox Serpent.

The redfox-old GitHub repo was (also) archived today, but this was probably to be expected; no clue as to why its successor suffered the same fate today ... As for the Eclipse Board , they mention "Temporary maintenance" (stress on "temporary" is mine ) ... That ; and those "proposals" did materialise into a Librewolf-ification of r3dfox that many, myself included, never asked for ... As @Jody Thornton put it, ... and I'll add Vista SP2 to the OS mix above ; yes, close to "stock" Firefox but with the ability to launch on older WinOSes! This is what most site admins expect, this is what most extension authors expect and target... I was never part of the "extreme web privacy" crowd to demand a change of route towards Librewolf (or similar forks); I understand a small portion of the LW code was needed to address a specific r3dfox technical issue, but that is different to incorporating large chunks of LW code "while we're at it" ... As if it wasn't enough to deal with Mozilla "breaking" things (and locking down the browser) with each major version update, an "average" r3dfox user has to deal with "r3dfox-specific" changes, too (ones that not always meet with said user's "approval") ... And my own words on DRM/EME: I found r3dfox maintainer's "obsession" about DRM simply "blown out of proportion"; he goes to extreme lengths to disable EME at buildtime, but the browser itself provides an easy way to disable EME at runtime, if one objects to it for whatever ideological reason... Let's face it; with Google practically owning the Web, they have leveraged the use of their own CDM (Widevine) in most media services, even the most obscure, but still free, ones... Yes, I totally understand the argument about "black-boxed code" etc., but DRM has become a necessary evil in the web era of 2025 and beyond... A lot of focus has been put on the VMP (Verified Media Path) requirement associated with the majority of the prominent/commercial DRM'ed Video+Audio services (e.g. Netflix, Disney+, Paramount+, Spotify, Tidal, Apple Music, etc.) as a reason NOT to implement DRM on r3dfox (because VMP entails a very large sum of money, paid to Google, for certifying the browser for VMP purposes), but what about the rest of the lesser known services that don't impose VMP with DRM? Jody's example of https://www.cp24.com/now/ is such a case, there are many others... The whole thing kind of reminds me, in some twisted way, of Moonchild and his own browser, Pale Moon, where he vehemently refused to implement DRM of any kind; but while Basilisk was still his, he allowed the DRM functionality inherited from his FxESR-52 forkpoint to stay enabled; that is, until the point he could no longer shoehorn-in upstream (Mozilla) DRM patches and, one day, DRM in Basilisk was declared such a big Evil that had to be completely excised! (NB: Latest Widevine CDM (a .dll) needs Win8+ to properly function; on Vista/Win7, some wrapper DLLs (e.g. borrowed from the Supermium project ) are actually needed to make it work there (and only on non-VMP services)). I believe so; he probably had a "hissy fit" and decided to "now I'll show you all", or I could be totally wrong and the GitHub repo archival was an inadvertent mishap ... ... You can count me as one (though I did not post in that thread...). Personally, I'll stick to older r3dfox-140.0.4; it will become my new "KafanMiniBrowser" for GitHub; I'm not that concerned about security patches, as long as GH works there (and it'll continue to work until 140esr becomes deprecated), I'll keep using it... In closing, I'm not being entitled or ungrateful towards the r3dfox author; huge thanks from my side for what he has offered to me over the last two years or so ...

StartAllBack 3.9.17

I did it for testing (manually applying 3dyd's changes to the source of official PyInstaller 6.17.0) and converting into a wheel (built with 32bit toolchain from here on Windows 10). pyinstaller-6.17.0-py3-none-any.whl (for XP) pyinst-6.17.0_yt-dlp_x86_XP.7z

no clue, check for upstream if problem persists. (but remember, youtube pushes AV1 content which is too heavy for old machines.)

fileextd.dll its a old rare file that provide some functions that xp useally dont have - it can be seen as kernel extender i dont know its origin either some say its from the xbox and a official file while other say its a handmade file by someone maybe we get some more information about it what i know is that it is shown as used library on microsofts website: https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-getfileinformationbyhandleex then "Kernel32.lib; FileExtd.lib on Windows Server 2003 and Windows XP"

The problem with the new topic lasted for a really long time, and only fixed now. I remember being unable to post on the Microsoft Office forum months ago. The Like button was used by a group of people with a leader whose name begins with "D", but they don't seem to be kiddies. I only use the like button generally when I've read what was said to me and don't want to reply anymore. While everything works, I'm keeping Supermium 132. Don't fix what isn't broken.

Hi, I just make a nice hack. I get a lot of Arduino nano for 67 Cent from China. They work under Win10 but not under XP SP3, "Unknown USB device". I use the Arduino IDE ver. 1.8.9 portable, means no installation. It has the exotic USB serial VID_0843&PID_5740. So, I take the win7 driver STM32_vcp_driver.zip from STMicroelectronics which has funny VID_0483&PID_5740. There I edit just the stmcdc.inf file only at this part ;------------------------------------------------------------------------------ ; VID/PID Settings ;------------------------------------------------------------------------------ [DeviceList.NT] %DESCRIPTION%=DriverInstall,USB\VID_0843&PID_5740 [DeviceList.NTamd64] %DESCRIPTION%=DriverInstall,USB\VID_0843&PID_5740 Right click on this modded stmcdc.inf "install", and voila, this Arduino nano clone from China works perfect under XP SP3 Dietmar

The 153 error relates to the referrer header – Google have decided that when embedding a video you can't block it any more. It's worth noting that when these useless error codes appear that you can right-click ... copy debug info ... paste that info somewhere you can read it, and then look towards the bottom for: "debug_error" The 153 error will reveal itself as: "embedder.identity.missing.referrer" which is the clue that it is caused by a missing referrer header. Ben.

No, not really. That is the "this is not an INSTALLER, just EXTRACT and EXECUTE" version. To make it PORTABLE, you have to "wrap it" wit a LOADER so that the .exe doesn't save files outside of its own directory, so that it doesn't make permanent changes to the registry, etc.

The way that I do it, it does not matter if there is a portable version or not - *ALL* Chrome/Chromium-based browsers 'can be made' portable Just replace the "bin" folder with the Supermium files that you want to turn into a portable version. You can start with anything that is already portable (360Chrome, PortableApps, WinPenPack, the list is endless).

@feodor2 released Mypal 74.1.4 some days ago. Today, I have installed it and made some tests. The good news: my favoured Alice0775 script loading method still seems to be working with this new version, without any additional modifications. The bad news: the Custom Buttons extension stopped working completely.

Not my fault, really, but here you go: https://board.eclipse.cx/viewtopic.php?p=7539#p7539 https://board.eclipse.cx/viewtopic.php?p=7542#p7542 https://board.eclipse.cx/viewtopic.php?p=7593#p7593 There was this r3dfox bug and the author (thought he) found the solution in one of LibreWolf's special "policies", but while he was "there", he decided to also implement several other LW policies/settings into r3dfox; this is implied in the bolded wording of every new "LW-ified" r3dfox release, e.g. 128.14.1esr: Testimonies of breakage can be found in the linked Eclipse Forum thread and in the GH issue tracker (recent open/closed issues), e.g. https://github.com/Eclipse-Community/r3dfox/issues?q= is%3Aissue state%3Aopen sort%3Aupdated-desc https://github.com/Eclipse-Community/r3dfox/issues?q=is%3Aissue state%3Aclosed sort%3Aupdated-desc What made me furious the most was this ; but, as I wrote already, I'm only speaking for myself here; it may well be that the majority of the r3dfox users are still very happy to have got new releases with the latest security patches, courtesy of Mozilla .. As you often write, "moving on" ...

I was worried that may be the case too, as I was a tad vocal on my thoughts of where r3dFox is headed, on the Eclipse Fourm. However, that isn't my saying "You have to do this or that!". I'm vehement on my opinions, and make no apologies for it. In any case, I have now moved on the Firefox for Windows 7 and 8, since releases seem to be happening more quickly. This is especially the case for ESR builds. I'm glad I switched. Even if my comments were not made, I'm sure there were a lot of vocal proponents of my mindset, including one being a moderator.

YES IT IS, if you really want us to seek out a solution. There are a *TON* of Chrome extensions taylored to VLC Player. ONE example -- https://chromewebstore.google.com/detail/open-in-vlc-media-player/kbonopecbfhedlfpaphndlaoppmdppim?hl=en Then browse the "related" and then browse the related's "related". *TONS* of them. Though I myself have not used any of them to speak towards any recommendation.

tried here on xp and 7 but I can't reproduce the crash. removing ID check means inappropriate extensions that can break browser hard can be installed. so I can't let this option available. if you are confident an extension that will work, open it up with archiver and modify its manifest adding my browser's ID instead.

Of course,. I said to @Dave-H some posts above the more the better and he agreed by replying the more the merrier.

But does anyone still use IE6 in Windows XP seriously? IE8 is crap but IE6...No way!

Very strange! WSUS server + WUMT was the first method which worked without any problems from the first time I tried. Yes, it's the same.

Thanks for your info! But where did I say that last verion is REV3d? I wrote: You probably misread it or missed it. I provided a download link for version REV3d because there is no link for version REV3e. @heinoganda hadn't provided any download links generally. You had to send him a PM to get his latest release. And he doesn't provide download links anymore. So there is only a download link for version REV3d. As I already mentioned in my article I did my job carefully: But no problem, that can happen to anybody. The Romans said: "Errare humanum est."

@Dave-H Requested certs have been sent via PM. And give your ProxHTTPSProxy a second chance by installing original certificate in program folder. For this purpose apply ProxHTTPS Cert Install.exe. Maybe your generated HTTPSProxy CA certificate is problematic when you try to connect to MU. You know my HTTPSProxy CA certificate has a different timestamp. And don't forget to close HTTPSProxy by clicking exit in systray menu if using ProxHTTPSProxy.

Of course the 10th of March 2021. I'll send you missing certificates as soon as possible. I think they aren't unique, only made for my system. They are from Microsoft. And try method "Turning back time" at all costs! But now Microsoft Update isn' t working anymore. You have to check all including status of all services. And please send me your screenshots listed by ServiWin. Comparing with help of your log file is too tiring.

@Dave-H Due to the fact that the Microsoft service HTTP-SSL was disabled in your system I think it is a good idea to compare our Microsoft services and their status generally to be sure all necessary system services are still working. There might be some services not being essential but anyway in my system Microsoft Update is working properly. To do that download the tool ServiWin 1.71 from NirSoft. Here is the homepage link: https://www.nirsoft.net/utils/serviwin.html and here the download link: https://www.nirsoft.net/utils/serviwin.zip. It's portable so there is nothing to install. I've taken two screeshots of all Microsoft services existing in my system listed by ServiWin. Columns with German description have been faded out. So it's much easier for comparing. Here they are: https://imgur.com/az67Jo6 and https://imgur.com/bIQ2jIN.

@maile3241https://imgur.com/AqLdRes Of course you have. In hexeditor all lines are arranged hexadecimal on left side. Find line 0000EC80 and then position (column) 4. Open your eyes! In your screenshot I can see the matching code.

@maile3241 At offset EC84, replace 83F89D7508 by 3BC0EB3290. But first check if code 83F89D7508 matches exactly in your file.

No, in step 3 there are three urls related to MU. Maybe you have missed it.

@maile3241 Where is it missing? In my third step I already wrote to add it to Trusted zone of IE. Maybe a little bit more explanation, please!

And this is a certificate updater to get the most recent root certificates: https://msfn.org/board/topic/175170-root-certificates-and-revoked-certificates-for-windows-xp/?do=findComment&comment=1095349

@Dave-H Maybe perform all steps in my new post: As I told you I had a lot of troubles to restore MU in my system. I had all error codes someone could get. I think your error code has been one of them. Maybe you have a BIOS date/time problem due to low cmos battery but I don't think so. My advice: Do all the steps once again and do not miss anyone! You know Windows is very often a mystery.
