Hi!

Version: FF Android 101.2.0 (plus other version stuff I can provide if needed), Android 12

Just thought I'd report this because it appears to be a consistent, reasonably long-standing issue (months) on a popular news site. Or is it "just me"?

Website: https://alightmotionapk.co/mod/

Expected behaviour: I am able to open links and download files on this website as backround tabs and continue browsing.

Actual behaviour: 1. After a couple are opened, Firefox for Android hangs for very close to 30 seconds then does a deep redraw/repaint of all tabs and continues to function until I next try to open another background tab from that website. 2. During the hang tab interface continues to redraw, but the pages are not repainted and no taps events work. 3. At the end of this hang time, the pages appear to redraw from scratch and the context pop-up for the third long-press appears on top of whichever tab I was looking at.

It is 100% repro for me -- long-press fails when attempting to open the 3rd background tab, but repaint failure occurs earlier. There is something toxic happening.

Curiously, when I next view my Android Home screen, there is some sort deep refresh/repaint, as if it has been swapped-out or GC'd etc.

e.g. Is there some massive memory blow-out happening?

Context/workarounds: 1. I have tried clearing all browsing data and using a guess account on the phone. 2. I have no addons installed. 3. Neither Chrome nor FF Desktop exhibit this behavior. This is FF Android specific

Thanks!
