Unfortunately, I don't have much hard data to present. Ever since I upgraded
to Firefox 98, my system's RAM (16G) and swap (2G) get nearly exhausted within
a couple of days of starting Firefox. Restarting Firefox releases all the
memory as expected and all is well for 2-3 days before the memory consumption
gets high enough to cause unnecessary paging. Before the upgrade to v98, I
used to run firefox for weeks without *any* issues like this.
Normally I use a couple of extensions, but I've reproduced it without any
extensions enabled.
$ grep firefox /var/log/messages

The firefox got killed because it ran the system out of memory on the 19th. I
restarted it, and after ~10 hours of mostly idling it was:

What the ps(1) output doesn't show is that the virtual size of one of the
processes seems to climb to as high as 25GB when actively browsing the web but
quickly drop back down to "reasonable" single digit GB.
Let me know what other information I should collect or what I should try to get
to the bottom of this.
