I do not know if other users are experiencing this. But my firefox 4 installation always freezes (not responding) for about 10 seconds whenever I try to launch it. Here are the extensions that I have:

  • Session manager
  • Grease Monkey
  • WOT


  • Download youtube videos as mp4


  • Flash

I'm currently at version 4.0.1. What can I do to solve this annoying problem?

Does it still freeze if you disable all your extensions? – William Jackson May 6 '11 at 2:58

1) Turn off all your extensions.

2) Switch them back on, one by one, until you identify the culprit.

3) Disable that extension.

4) ???

5) Profit.
