It happens on things like forums or whatever long pages that I have to scroll down. It only happens occasionally and for less than 10 seconds, then it jumps to wherever it should have been if the scrolling was working. I can also unfreeze it by clicking open something else like the OS menu
Disabling hardware acceleration, fresh install, etc doesn’t solve the issue
It only happens on Firefox and derivatives, Vivaldi has never done it after many hours of use
The problem started sometime in the last few weeks and is the same for wayland or x11 across multiple distros
If it’s not an extension, Wayland, X11, or hardware acceleration, happens even with derivatives, happens on multiple systems, and reinstalling doesn’t matter, then the last thing I can think of is your Firefox settings folder. Usually .mozilla, but could also be .librewolf, .firedragon, etc.
Do you sync the accounts or manually copy/sync the settings files?
Every other variant that uses the newest version freezes
Somewhere around version 134 is started happening across all variants and distros for me, but Floorp is 128 and has no problem so far after a couple hours of use
I’m having the same problem. It seems to only happen when I’m scrolling in Firefox. Like you, the only extension I’m using is uBlock Origin and it doesn’t seem to matter if I have one or many tabs open.
It’s just on the newest versions of Firefox. I have ublock origin with the same filter lists running on Vivaldi and an old version of Firefox with Floorp, and they both work fine
