Ever since upgrading to Firefox 4 (Ubuntu 10.10 64 bit), anything with a lot of scripting (e.g. Facebook, Google Image Search) runs incredibly slowly.

For example, clicking on a picture on Facebook hangs the browser for a good 30 seconds until the picture overlay crops up. Google Image search is about as bad. It seems like the more scripting of some kind or another is on a page, the longer it takes. So pages that pull a sidebar from a database somewhere are laggy for awhile until it loads, but then are fine.

Thought I'd fixed it, but not so much.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).

  • Don't make any changes on the Safe mode start window.

Follow the instructions at this page. They worked for me at least.
