Starting with build version 101.0-2.fc36 I get memory leaks when browsing multimedia-heavy sites. Killing tabs from the integrated task manager doesn't help, I have to restart Firefox.
I tested firefox-101.0.1-1.fc36 and also Mozilla's 101.0.1 binary with clean profiles. There were no issues with the latter.
The quickest reproducer I found was logging into hero-wars.com (requires login) and within seconds, all the RAM fills up.
There are no issues with firefox-101.0-1.fc36.
Intel graphics, x11 session.
What does say about:memory? Please attach your about:support.
Also can you test latest mozilla nightly?

about:support and about:memory reports
I did three tests: one with firefox-101.0.1-1.fc36, one with Mozilla's 101.0.1 and a third one with the 103.0a1 Nightly.
I have included the about:support info from all three and the memory reports before loading the game and after letting it run for a few minutes - I hope they are useful. If you need something more concise, please let me know what.
I hit the same issue with the Nightly.
Thanks. If you see the regresion on Nightly too it may be from https://bugzilla.mozilla.org/show_bug.cgi?id=1735929
Might be nice to find an example that doesn't require a login (I've got the same problem, my reproducer is a zoom session so that requires two people to reproduce).
This is probably a dup of bug 2095791
Can you try a general WebGL example from https://webglsamples.org/ ? For instance https://webglsamples.org/aquarium/aquarium.html or https://webglsamples.org/blob/blob.html ?

memory reports before and after running the aquarium demo

It takes a bit longer, but it happens. With 101.0-1 memory usage remains constant after loading the aquarium demo, whereas with 101.0.1-1 it increases linearly.
I've uploaded the memory reports of the run with 101.0.1-1, just in case.
Upstream bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1773953
Running 101.0.1-4 I can no longer reproduce the issue, feel free to add this bug to bodhi when you create the update.
Thanks a lot Martin!
