Firefox stopped working the other day and I can't get it to work again. When I try to run in, it just hangs there, CPU goes to 100% (according to "top") and it will shortly ask me if I want to keep waiting or force quit (waiting does nothing).
I have purged firefox
deleted ~/.mozilla
deleted /etc/firefox/
deleted /usr/lib/firefox/
deleted /usr/lib/firefox-addons/
Tried to run in --safe-mode several times, nothing seems to work.
Now I have tried to submit this to ubuntu running ubuntu-bug firefox
and I see several errors in there but I don't know where to go from here. Googling those errors didn't help. Can anybody please help me to continue troubleshooting in some way?
Edit:
Using the default firefox installed from the local repository: Mozilla Firefox 78.0.1
Ubuntu version: Ubuntu 20.04 LTS
I have also tried to run firefox directly from the file I got from firefox.com but had the same outcome.
Edit2:
This first happened when I tried to run firefox from a script using Selenium and the Firefox Gecko Driver. At the time, I had an instance of firefox already running and the script quit with a connection issue. Closed all firefox windows and it didn't work anymore since then.
It had never done this before while I have tested the script and used it a lot everyday. I also tried to delete the gecko driver from the $PATH.
