For some reason in Firefox I'm not able to scroll the content if the window is not focused. I don't know when and how this changed and I can't find a way to fix it.

I noticed this doesn't happen with other applications - I checked with Libreoffice Writer, Falkon, Chromium.

Could this be a per-app setting that was changed? Anyone has any idea?

Here's my system info:

Code: Select all

Operating System: Fedora 31
KDE Plasma Version: 5.17.4
KDE Frameworks Version: 5.64.0
Qt Version: 5.12.5
Kernel Version: 5.3.16-300.fc31.x86_64
OS Type: 64-bit
Processors: 8 × Intel® Core™ i7-8650U CPU @ 1.90GHz
Memory: 31.1 GiB of RAM

An update: I noticed this only happens when using the mouse. If I scroll using the trackpad, it works. Same for trackpoint (I'm on a thinkpad).

That does seem a little weird, but it sounds like it is something specific to Firefox, so you might check their forums.
