I am using Firefox 3.6.13 for Mac. I disabled Javascript (in Preferences) to see if it would affect problems with browsing speed. I then discovered I need Javascript for my email, so I went back to Preferences to enable Javascript, but when I click on Preferences now, nothing happens.

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 > Themes).

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