Downgraded to version 87 and happy days.
Works for me. Did you try with fresh profile (firefox
-ProfileManager), mozilla's binary (package mozilla-firefox-bin)
and in case it still doesn't work stracing it?
I tried with fresh profile - the same effect. It seems like FF is
reacting for clicking, but doesn't "re-paint" the interface
accordingly.
When I, let's say click "+" to open a new tab, then minimize the
window and restore it, the new tab is there. Double-clicking on the
window title (maximize/un-maximize) also refreshes the interface.
Firefox 88 from mozilla-firefox-bin behaves the exact same way.
Would you mind telling me how to strace the program in a correct
way, please? I did it few times in the past but always I was
googling the method.
Ah ok, somehow I thought firefox hangs or fails to start for you.
That's probably an effect of enabling WebRender by default for
XFCE/KDE with Intel/AMD GPU so likely for you. Try disabling
webrender in about:config (|gfx.webrender.force-disabled=true). Which
GPU? If Intel are you using modesetting driver?
Zwycięstwo! Setting up the gfx.webrender.force-disabled=true made the
firefox usable again. Thanks Jan!
Regarding the modesetting, I don't remember if I was tweaking any X
config about that. My hardware is:
CPU: Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz
GPU: VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)
And xorg.log:
# grep modesetting Xorg.0.log

Not using modesetting on Intel is your real issue. Try to figure what's
missing to make it work and webrender most likely will be fine in
firefox. Anyway if you still have issues the discussion should be moved
to pld-users-*
