Let's hope that's not the case, Roy. Always grateful for your releases... and that's an understatement.

I wanted to tell you all that I have been experimenting with Windows 7. It seems to be a reliable, stable, lightweight operating system. It runs smoothly. In fact, it boots faster than our dear old XP. I've slapped it around a bit and it holds up very well to the abuse.

Firefox is still compatible, although the latest version does not support some extensions that I use and miss very much. Another problem is that it consumes a lot of memory... a lot. Having 4 or 5 tabs open means more than 2gb of ram gone.

I've taken the opportunity to test the latest version of MyPal -thanks Feodor- and it seems to work very well. At memory level it seems similar and I still could not test if the extensions I use are compatible, but the good news is that Whatsapp Web works.

Still... I could not get used to Windows 7. It offers some compatibility but several key programs are no longer compatible. So for now I'm sticking with XP.

I applaud your words about Windows 7.

But unfortunately, Firefox's support for Windows 7 is coming to an end soon. See this article. As for your issue about too much memory consumption, multi-process mode is probably the reason behind this.

Thank you. I'm loving Windows 7. I installed the minios version. A lighter and improved version. I realize as I put hours on it that the real problem is not only the non-compatibility. The problem is that programs that in XP work, in Windows 7... simply can't get them to work right. Lots of errors that I can't find info on and I end up in a dead end. I ended up doing a dual boot with XP and 7 to split tasks. It works for now.

Well, I assure you that I can sniff out their play. That's why I keep testing MyPal, but it's also giving me headaches. Memory wise it works better than FF, but it won't let me install any extensions. When I want to search from the address bar, it won't let me search. I will try to spend more time on it and not lose patience. I will look for info regarding what you say about multi-processing, which seems to be the case. Every time I use FF and open the task manager to see why my ram disappears there are thousands of FF processes there.

Yep, multi-process mode is the reason for this, it splits FF into multiple processes so that FF performs faster by making it use more memory. It's has been enabled by default since FF 54.

I also remember there is an extension for manipulating network request responses, which I'm not familiar with, but anyway, another way around the problem is with a user script, something like this:

document.querySelectorAll('link[rel="preload"][as="style"]').forEach(e => {
  const n = document.createElement('link');
  n.setAttribute('rel', 'stylesheet');
  n.setAttribute('href', e.getAttribute('href'));
  const m = e.getAttribute('media');
  m && n.setAttribute('media', m);
  e.parentNode.replaceChild(n, e);
});

Put the code in your favorite user script manager and make it run on document-end (should be default).

You're probably remembering JustOff's "Modify HTTP Response," which is how I initially solved the issue; but I think your user script is a better solution for me since, e.g., ViolentMonkey will run in multiprocess mode, while JustOff's extension won't.

BTW has anyone yet noticed similar CSS breakage on GitHub? M$ seems determined to break any browser that won't run on Win 10+. Edit: Well, it works in a clean profile.... I wonder which extension or config setting only breaks GitHub? Edit 2: Well, it's uBO. (Grr.) Strangely, though, when enabled, GitHub breaks - yet uBO doesn't report blocking anything! How am I supposed to tell what to unblock?

For legacy extension support, you could try Waterfox Classic. (I've heard good things, but I haven't tried it myself.)

For the memory consumption I'd suggest JustOff's "Lull the Tabs" extension, although I suspect it's a legacy extension that'll only run on Waterfox Classic.

Perhaps comparing network traffic with "your BO" (that's just what I "read" whenever people type "uBO", waka waka waka) enabled versus disable using DNSQuerySniffer &/or TcpLogView (both by NirSoft)?

Also, are there any errors/warnings shown in Dev Tools?

Can you provide a screenshot of this breakage? When did this start happening? As we all know, uBlock Origin can be used in two different modes, a standard and an advanced user mode. Which one do you use? In the case, uBlock Origin does not report blocking anything on GitHub, you could check uBO's general settings in the option page. Maybe, one of these settings is problematic when loading a GitHub website. But this is just a theory. When I am back at my desktop computer, I will have a look in my configuration of uBlock Origin and check what happens when accessing GitHub.

All more recent browsers show these behaviour. If you have a lot of RAM, it should be not a problem at all although I don't like such consumption.  My Windows XP Professional computer is very low on resources. Only 1.5 GB RAM. One of the reasons I appreciate @roytam1's browser so much. On my machine, they are running in single-process mode, consuming RAM as they actually should do. Additionally, I installed Mypal 68 from the very first and also configured it working in single-process mode. It works great, and its RAM usage is low.

I don't use that unnoficial W7 lite crap made in south America.

I have heard many times the original chrome is a notorious memory hog but I'm unable replicate this behavior here.

I can have 50 tabs open at a time with just about 3.5GB of RAM and for XP use I would highly recomment you the rebuild from @NotHereToPlayGames

No disagreement.

Although users should be reminded that it was "Meltdown" and "Spectre" vulnerabilities that largely brought about the need for multi-process versus single-process more so than the increased number of multi-core CPUs.

MSFN Members were quick to point out that Chrome and its forks can have site isolation disabled and reduce RAM 20% or so but that Chrome itself would prefer you use a different browser then use theirs with site isolation disabled.

Has the same level of scrutiny been applied to disabling Mozilla's site isolation topology?

Low-on-resource users must weigh the pros and cons - but they should also be aware of those pros and cons.

If "Meltdown" and "Spectre" scared you into losing sleep when their tentacles were sprawling the internet, then you should think twice before disablling site isolation (which in the case of Firefox and forks, single-process = site isolation disabled).

 

edit - I used to shout from the roof top that single-process was "superior".  I can only speak from my own paradigm, but to me, RAM consumptions had me "blind-sided" and viewing browser performance through a tunnel-vision lens.

It took me a LONG TIME to break myself from that perspective.

EVERY COMPUTER is different, so this is not a "blanket statement", but what I started doing is looking at SPEED instead of RAM.

If a computer running at 80% of RAM being used isn't slowing anything down, then why run the risk of "Meltdown" or "Spectre"?

If the SPEED of everything is the same at 20% as it is at 80%, then why is the sky falling when we coast around at 80%?

Again, that was just MY paradigm-break.  We all know our own computers better than others, so everyone must "decide for themselves" what works for them and what doesn't.

For the memory consumption I'd suggest JustOff's "Lull the Tabs" extension....

... and/or (as others here have suggested) just switch off multiprocess mode: https://techdows.com/2019/08/multi-process-e10s-can-still-be-disabled-in-firefox-68-or-later-versions-here-is-how.html

Mozilla made it harder in FF (and consequently MyPal) 68 and above; you now have to set a Windows environment variable vs. just changing a pref in about:config, but it's still doable.

N16s is quite likely correct that forcing single-process mode increases vulnerability to Spectre/Meltdown attacks (and that probably applies to Serpent as much as FF or MyPal); hence the increased difficulty shutting it off. But if the browser hogs too much virtual RAM, it'll start thrashing and end up having to be shut down and restarted, so if you have little physical RAM (regardless of OS) it may be worth the security trade-off.

I would highly recommend you the rebuild from @NotHereToPlayGames

But remember, a major reason for the OP preferring FF-based browsers was to keep as many of his legacy extensions as possible, which I why I suggested Waterfox Classic. If one uses a lot of extensions, switching browser platforms becomes a major hassle.
