Firefox 144.0 on a W11 PC with all updates.

Firefox is running multiple (10-13) windows with 5-10 tabs each. Even if all Firefox windows are minimised and not being used, memory usage goes up all the time. It is currently, according to Task Manager, using over 5 GB of 32 GB of available memory. CPU is sitting at ~4%. Individual tabs, like Youtube watching CNN suddenly freeze and are no langer accessible and can't be unfrozen by anything I have tried. Even the mouse pointer is not displayed inside this tab I need to restart the entire PC several times a day only to have Firefox usable. I have turned off efficiency mode, but this did not change anything. I'll include a system snapshot with msinfo

Any ideas?

i can not access any of my yahoo accounts, i continue to get a pop up screen that says the "to many request" why should i continue to use firefox / mozilla. it keeps crashing and having issues. freezing and taking forever to load. restart everyday

Hello, dear Mozilla support team :).

I have a question that has to do with the ever growing memory usage. I just found out the about:memory page in Firefox, which allows the users to manually free up the system memory by clicking the "Minimize memory usage" button. This is great and it does its job well, however for many years I've wondered why doesn't the browser clean up the memory taken by web pages like Twitch, Kick, Youtube, etc., which take a lot of memory, especially when people leave them open for hours, then when they close the tabs, the memory stays buffered until the browser has been completely closed.

The "Minimize memory usage" button does clean up the memory, so won't it be possible to implement such functionality that can be enabled/disabled somewhere in Settings, to allow the users to choose the browser to unload all memory taken by any tab when they close the tab, but not the whole browser?

This will help a lot, because I personally leave my PC and browser open for days, and sometimes I have to either close and re-open it, or go to about:memory and do a "Minimize memory usage" to free up the memory, that was taken few days ago by a single Twitch stream tab or some other tab, and the information in this buffer is absolutely pointless, but it sometimes takes all of my 96GB of RAM.

Thank you for any information on the subject :).

All the best, Borislav.
