Long running tab (kiosk), 100% CPU
Probably your best bet is to use the Firefox Profiler once it starts hogging the CPU to try to see what it's doing. I'd be happy to take a look at the result although I don't have a lot of experience at diagnosing performance problems; hopefully the profile will make it obvious what's going on.

Slow Firefox Startup
I tried using the https://profiler.firefox.com/ and running with:

Definite tab bug affecting both Win/Linux intermittently
You can try to reproduce while taking a profile using the Firefox profiler, then share it in the #perf:mozilla.org room on Mozilla's Matrix instance.

Why does Firefox run slow
Run a profiling session for ~30 sec when you notice something is running slower than you expect, see https://profiler.firefox.com/. Share results here if you want help interpreting them.

Problems with Firefox non snap versions on Ubuntu 22.04?
Next time, send a SIGABRT to the main process (kill -6 $(pidof firefox)) and use the resulting backtrace (you will find a link to the crash report in about:crashes) to file a bug. A performance profile could be useful, but you'll need to know first what to capture. This seems like a graphics issue, so try the Graphics preset. Share a link to your report.

Dear Firefox, why are you so terrible at rendering Flutter web apps? It's like potato quality.
https://profiler.firefox.com will be useful if you can capture and share it to developers.

Webpages not loading or taking forever to load
If you can reproduce it in safe mode and a clean profile, capture a performance profile using the clean profile while trying to load a problematic webpage, don't remove any information from it, and share it here (although it's typically not easy for users to analyse them), or file a bug with it attached.

Firefox hangs on Facebook page
Next time, capture a performance profile using the Graphics preset, and kill the browser by entering kill -6 $(pidof firefox) in a shell. This will create a bug report (unless debian disables the crash reporter) that would indicate where Firefox is stuck at. You might need to use an official build to get useful results.

It's getting hard to use and recommend Firefox, I'm afraid for the free web
Re: firefox and privacy, if you want to use firefox for privacy, consider using https://github.com/arkenfox/user.js . There is a case to be made that Firefox (with arkenfox's user.js) is one of the best privacy-respecting but still fairly usable browsers.

In 2024, please switch to Firefox
For extensions, I recommend people follow the recommendations[1] in the arkenfox repo and either harden their firefox or use librewolf. Umatrix is unmaintained since 2019.

Waterfox G6.0.2 had whitelisted search deal partner www.bing.com against user extensions in extensions.webextensions.restrictedDomains
If you make time to dig through settings and change them away from their official use (99% of users don't), then you should use a customized setup (in this case, a user.js). That way, you're good to go no matter what Firefox fork you use.

Google Chrome just rolled out a new way to track you and serve ads
> Firefox remains a stable option to come back to everytime
Don't get me wrong, I've been using Firefox for the last decade and I don't intend on using anything else for the foreseeable future, but Mozilla has no idea what they're doing with Firefox nowadays. Firefox View is the most useless thing I've ever seen, that expiring "independent voices" theme picker was some weird hippie stunt[1], the latest UI redesign which split the tab from the window looks hideous, and it's not like Firefox doesn't have things you can tweak for a more private experience[2]. I miss Firefox Test Pilot where they tried out different new features, I found a lot of them to be very useful but sadly lots of them didn't make it.

I don't understand what's so good about Firefox
Like others have said you can customize the browser to the point that it doesn't even look like the default anymore. Or customize it to maximize privacy.
