Firefox Browser - Fedora vs. Mozilla (official) builds

I’ve noticed essentially three things not noticable with the official build:

  • it is noticeably slower inside web-apps (e.g. cryptomininggame.com)
  • in YouTube it switches after a while down the resolution in “auto”-mode (sometimes to SD-resolution, even with perfect network connection)
  • my ad-blocker is not working (AdBlocker Ultimate) even though it shows blocked content

Anyone else having those issues?

For the time being as a work-around I’m downloading from Mozilla and copying over the into /usr/lib64/firefox/…

Seems to be fixed with firefox-82.0.2-3.fc33.x86_64.rpm - closing
