I confirm that I use Firefox.

Great, thanks a lot for the suggestion!

I'll try this on Monday...
I will also try running Plasma without Firefox to check if I still see graphic
corruptions... Graphic corruptions are my main problem because I do not know
how to recover from them without rebooting, whereas the kernel is able to
recover by itself from the GPU hang :>.
<span class="quote">> What version of firefox are you using?</span >
60.0.1 (Ubuntu build) or 60.0.2 (Mozilla build). I also sometimes try beta and
nightly versions from Mozilla, and snap and flatpak builds.
<span class="quote">> Any particular setting that isn't the default?</span >
In about:support I have:
Compositing OpenGL
instead of the default
Compositing Basic
In about:config that is:
layers.acceleration.force-enabled : true
layers.omtp.enabled : true
I've been running Firefox like this for years and never had problems before.
I have many other "modified" settings, too many to list here.
Thanks again,</pre>
