I am curious if this creature may provide a summary on user-space OOM 
killers. I have never tried them, but I expect that they may be more 
intelligent than the kernel-space one. I have seen mentions of the 
following ones: earlyoom, nohang, oomd.

Do you have AI browser extensions that may load huge models in respect 
to memory footprint?

It is just a process that is responsible for some web pages. JavaScript 
loaded for particular sites may leak. Videos may consume RAM as well. I 
would not rely too much on ability of an application to recover after 
killing of its specific processes. From my point of view it is better to 
restart Firefox in such cases.

Perhaps it is possible to find a particular site that causes issues, but 
you need to inspect system namely when it is becoming sluggish.

Firefox has the about:processes and about:performance tools. They may be 
accessed from the about:about list.

Try to sort top(1) output by memory ("M" key), try df(1) to check tmpfs 
usage for the case that enough temporary video files are stored there.

I believed that 32G of RAM is still above that "average" users have, so 
it should be enough. Other suggestions surprised me that 0.5G of swap 
may significantly change anything since it is less than 2% of RAM.
