Dramatic Slowing Down on MacOS

[lharriso]

Preliminary Checks

• I have read and understood the important section above.
• I have searched existing issues and avoided creating duplicates.
• I am not filing an enhancement request.
• I have checked that this issue cannot be reproduced on Mozilla Firefox.
• I have checked that this issue can be reproduced once I removed all my Mods and Custom CSS.

What happened?

Hello all,

Im writing to share that I've experienced a lot of slowing down recently while browsing, for instance, youtube doesn't even load anymore and neither do google searches.. basically the browser becomes totally unusable.
I cleared the cache and this seemed to fix it temporarily, however not even a few hours later the issues came back, so I removed all extensions (potentially causing excessive memory usage in the cache + cleared startup cache) but the issue keeps coming back.

Im currently using the most up to date version of the browser on MacOS (1.21.9b (Firefox 153.0) (aarch64))

No idea if anyone else is experiencing this issue or not but it could be quite serious

Expected behavior

The browser is not expected to slow down so often and by so much

Actual behavior

It is expected to manage the cache better and not slow down so drastically to the point of becoming unusable

Steps to reproduce

Keep using the browser for long enough on macos, go to youtube, google etc.. and it will end up slowing down to the point of becoming unusable, or you have to fix it every few dozen minutes (also very annoying to do while working for instance)
