I see the same with firefox on my FreeBSD daily driver machine.

I thought it was because I pause the entire firefox process when the screen is locked. When it resumes it sometimes acts up (I use the STOP and CONT signals for this). But maybe it's just a FF bug.

I just restart it once every few days, my OS doesn't actually become unstable due to it. But i do have 64 GB of ram (one of the benefits to no longer being tied to apple's ecosystem is that memory upgrades and amazingly cheap)
