Post a screenshot of the the performance tab from task manager? Just want to see you computer specs.

I open double the number of tabs in Brave and Chrome (as those in Firefox) but I almost never need to terminate their processes.

This started around the end of last year. Could be gold-plating in the Firefox codebase? Please revert to some earlier release.

Hi

Do you have many tabs open on Firefox?

Do you have any add-ons installed?

If Firefox is consuming too much memory, you can pause some expansion features and disable some paging to reduce memory usage.

I have, at any given time, - 6 tabs in Firefox - 8 tabs in Brave - 12 tabs in Chrome

The only Firefox extension I have installed is EditThisCookie and it's disabled.

Enabling hardware acceleration and deleting the content-prefs.sqlite file as recommended here https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources didn't help.

How can I pause some expansion features and disable some paging?

yeah, i have the same issue and recently in 2 weeks or so it went to the worse side of the spectrum again and now i can open 2-3 windows max, while previously it was atleast 6-9 windows.

plus i could probably even check when it was at the good side recently (couple of months ago, but even that only for a short period of time). and 1st it started to go on the wrong side like 1-2 years ago already (before that it was always very good)

(i have 32gb ddr4 ram)

@screenshot it don't seem like they can do shit about it, hence my very fitting username!
