A lot of video and otherwise news and search and GPT4

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?
When the system starts to become sluggish, have you looked at the
firefox 'Task Manager' under tools to see if anything stands out?
Previously I have seen the Isolated Web Co processes maxing CPU and
the CPU fans starting to roar. Nothing unusual in content at the time
and if I kill all ESR related processes it quiets down and I can
resume the closed windows and tabs at much reduced CPU
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.
