Firefox 145.0.2-1 is already in Testing and Unstable;
perhaps that’s indicative of a problem with 145.0-1, but I haven’t seen it.

You’re using Plasma, just like me, are you not?

You could try resetting firefox to see if it makes a difference – make sure your Firefox sync is updated first do you can easily restore bookmarks and extensions.

The usual instructions:

Does it still occur in a fresh (Manjaro) user account?

If there’s still a problem after the usual housekeeping, I’d tend to rule out Firefox as the culprit.

Coming soon:

There will be some changes to Firefox 147.0 – new installs will no longer have profiles under ~/.mozilla, but will instead be placed in recognised Linux directory heirarchies; under ~/.config for example.

After that change:

  1. Make sure Firefox sync is current.
  2. Uninstall Firefox and delete/rename ~/.mozilla (only Firefox uses it)
  3. Install Firefox again and allow it to Synchronise.
  4. Logout of Plasma, login via TTY, delete ~/.cache
  5. Logout, switch back to SDDM and Reboot.
  • ~/.mozilla will no longer be used after this and can be deleted.

Mod edit:- Typo and context corrected. Changes relate to Firefox 147.0

Thanks for the propositions,
but i don’t think that this is a me problem. The first Firefox instance is working flawless to 100% and i think the second instance having a chance for this issue around 30% showed again but there must be some flaws around the new firefox version.

I just wanted to know if there is another guy here who also faces this issue or not.

I have to many individual settings to restore for a minor problem my whole firefox profile… it would be a shoot in my own leg. But thanks for that info’s anyways.

There must be bigger problems, before i would reset my profile from firefox.

Yeah Plasma with X11 at stable branch. I was thinking it could be maybe related to X11/Wayland.
