Try these steps:

  1. open the terminal
  2. type sudo apt update && sudo apt full-upgrade (this command will update all your installed applications and can take a while; if you don't want to update your apps, you can leave this step out)
  3. type "sudo apt install firefox" (you need root privileges)

First install method was with Ubuntu 20.04 installation. The second i rename Mozilla directory and from installed Ubuntu reinstall Firefox there was no improvement. There is only one user and that is me. I had on this computer a previous Ubuntu version (16.04) with Firefox and Thunderbird working correct.

Firefox is completely updated, but still hanging

Ubuntu 18.04.1 Firefox 91.0.1-1

Chrome works fine, but I prefer Firefox

I'll launch FF, see if the scroll bar works on a very simple html site, it lags. If I close it quickly, my whole machine doesn't hang. If I let it run, I can't even switch over to a terminal to kill it.

Please fix it.
