Google breaks search for Firefox users because of bad UA string sniffing
The thread is very long, here is the relevant comment:

Chrome's next weapon in the War on Ad Blockers: Slower extension updates

Microsoft Teams (which I don't think many people use voluntarily) in particular breaks in stupid ways - and then in others if you spoof your user agent.

"This video is either unavailable or not supported in this browser. (Error #4000) " on twitch with new laptop
a link to the video would help with troubleshooting, seems like another case of "this site or this particular feature doesn't support firefox" otherwise report to https://webcompat.com/

Hamrobazaar not opening in Firefox
Have any of you faced this? If the website is made to open only in chromium-based browsers, I am planning to report to Webcompat. But before that, I thought I would make sure from others. Any experience or quick fix would be appreciated.

Switching from Chrome to Firefox? Here Are Some Tips
Teams was a classic hellhole for me when I was using Linux. Nowadays it lets you in but Firefox genuinely doesn't support all of the features the Teams site uses. This means certain features are made unavailable to Firefox users. Forcing the user agent makes some of these partially work but they are also still broken so Mozilla doesn't want to enable a user agent override by default and Microsoft doesn't want to enable a feature that only half works.
This GitHub WebCompat issue serves as a good example history https://github.com/webcompat/web-bugs/issues/77892

Firefox Finally Outperforming Google Chrome in SunSpider
having recently looked at a firefox performance regression for filing a bugreport, tooling that tracks performance (quite publicly) sees attention, easy upload to share tracing profiles also helps: https://firefox-source-docs.mozilla.org/testing/perfdocs/ind...
Their dedicated blog keeps you posted if firefox perf is your interest https://blog.mozilla.org/performance/
If you have a particular website you notice chromium being significantly faster with, for an easy report, there's https://webcompat.com/ - though bugzilla is better than it seems when coming from github issues

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

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.
