Firefox (v96) on Linux - anyone finding it going squirrelly lately?


May 19, 2011
I think it started yesterday - I was browsing a few sites and when loading new pages in various tabs suddenly they stopped loading pages for any site at all. GeckoMain sat there saturating a CPU core, closing Firefox resulted in GeckoMain continuing to sit there and saturating a core. Terminating GeckoMain would allow me to restart Firefox but with the same problem straight away. The problem survived a reboot as well. Another Firefox profile didn't immediately have the problem, leading me to think it was profile-specific, so I 'refreshed' Firefox, reinstated UBO and everything was OK for a while, then the problem started again but went after closing Firefox and killing GeckoMain I think.

It's happened once today and went away after closing FF + killing GeckoMain.

I'm using Kubuntu 20.04 LTS.
