When I enter about:config into the adress box I get only an empty page. The about:config works normally on safe mode.

I have tried to check all boxes in the safe mode window, this did not help. I even manually disabled all add-ons and plugins, but this didn't help either.

Any ideas what to do?

Try to disable hardware acceleration in Firefox.

In Firefox Safe mode these changes are effective:

  • all extensions are disabled
  • the default theme is used (no persona)
  • userChrome.css and userContent.css are ignored
  • the default toolbar layout is used (localstore-safe.rdf)
  • the Javascript JIT compiler is disabled
  • hardware acceleration is disabled
  • plugins are not affected
  • preferences are not affected
