Why is Firefox typing and cursor are slow upon a normal startup but everything works well when I restart in safe mode?

When I open FIrefox normally, the cursor movement is very jerky - seems to get stuck on every link. In addition typing in any box is delayed. When I restart with add-ons disabled and in safe mode, the cursor moves fine and typing is normal. I have disabled all my add-ons but that doesn't seem to help as each time I restart, the jerky cursor and delayed typing present again. What is wrong?

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
  • the Javascript JIT compiler is disabled
  • hardware acceleration is disabled
  • plugins are not affected
  • preferences are not affected
