Does anyone can test http://turnjs.com/ on Firefox? I tried one and it's broken since Firefox nightly 122.01a
It seems broken for me too on 122.0a1 nightly. Can you use mozregression to narrow down when it happened? That would greatly help narrow down what part broke, and help to file an informative bug.
-
Any advice for dealing with webpages that do not function correctly on Firefox?
If you think it is a regression in Firefox, you can try mozregression: https://mozilla.github.io/mozregression/
-
Cannot scroll on chat gpt on mac os
If you want to find the bug, you can run a mozregression to find what broke it.

Problems with Firefox non snap versions on Ubuntu 22.04?
In my experience it's always Mutter, but it seems the type of issue where mozregression can help you find the exact problem.
-
Twitter not highlighting/underlining
If this is a regression on Firefox's side, eventually even the ESR will have the same issue. If you can, use mozregression to find the offending changeset and file a bug. Share the link to your report if you do.
-
video's audio lags when watching videos
That could be an issue with the site's media format that Firefox doesn't workaround, or a bug. Test in safe mode, and Nightly. If you can reproduce it on Nightly and this is a recent issue, find the regression window using mozregression and file a bug. Share a link to your report.
-
Inconsistent lines appearing on top border when hovering on Tabbar/toolbar controls - Firefox 113
I'm not sure what black line you see, but these issues are usually resolved by updating one's GPU's drivers. If you end up filing a bug, and you can reproduce the issue consistently, try to find the offending commit with mozregression.
-
does anyone actually use firefox or everyone here is on nightly ?
I've used Firefox, for free, for over 15 years. Reporting bugs is the least I can do. Mozregression makes finding a regression bug an easier job.
-
Firefox not loading vs Chrome?
Go try the mozregression tool. It's basically a program meant for debugging problems on Firefox. You can use it to download and temporarily run any version of Firefox (all the way back to version 1 I think), including nightly releases. You just pick a version of Firefox, enter a web address, it then downloads that version of Firefox and starts running it. You can use it for however long you need for testing. It's not meant for normal usage as it doesn't save any user profile stuff.

Someone can help please
Nightly? Use mozregression: https://mozilla.github.io/mozregression/

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:
- Firefox Profiler
-
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.
