Bugzilla

Hi robbie

I tried this today with the latest release version 80.0.1 on ubuntu20, sadly i dont have fedora at hand and i am unable to reproduce.
I need would need a memory report from about:memory, here are the steps:

Wait until Firefox is consuming a large amount of memory
In the URL bar type about:memory and press enter
Click "Measure and save" (optionally with "anonymize" checked to hide URLs, although this will likely make it more difficult for us to figure out which site, if any, is causing the leak)
Save the memory report somewhere
Attach the report to this bug


Another thing that i would need:
1) please retest issue on latest nightly build, can be downloaded from here: https://nightly.mozilla.org/ and retest the problem.
2) Capture a performance profile using the Cleopatra add-on. You can get more info on how to install and use the Cleopatra add-on (that helps you get the performance profile) by going to:
https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Profiling_with_the_Built-in_Profiler
https://perf-html.io/
Please also note that this add-on works only on FF Nightly, so that means you need to be able to reproduce the issue on Nightly first.

Please also check if issue still happens on the latest nightly build
With a new profile: you have the steps here:https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager

Lastly test if the issue is reproducible in safe mode, here is a link that can help you:

Hi robbie

I tried this today with the latest release version 80.0.1 and nightly version 82.0a1 on Ubuntu 20.04, sadly i dont have fedora at hand and i am unable to reproduce.
It would really help if you can provide a memory report from about:memory, here are the steps:

-Wait until Firefox is consuming a large amount of memory
-In the URL bar type about:memory and press enter
-Click "Measure and save" (optionally with "anonymize" checked to hide URLs, although this will likely make it more difficult for us to figure out which site, if any, is causing the leak)
-Save the memory report somewhere
-Attach the report to this bug

Another thing that would be great to have:

Please retest issue on latest nightly build, can be downloaded from here: https://nightly.mozilla.org/ and retest the problem.
Capture a performance profile using the Firefox built-in profiler. You can get more info on how to install and use the Firefox built-in profiler add-on (that helps you get the performance profile) by going to:
https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Profiling_with_the_Built-in_Profiler
http://profiler.firefox.com/
Please also note that the profiler works better on Firefox Nightly, so it's better if you are able to reproduce the issue on Nightly first.

Another thing that would be nice to try is running firefox with a brand new profile: you have the steps here:https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager
