My Hotmail e-mail start page opens but I can't read or delete e-mails, search e-mails, change folders. MSN says it is a problem with the browser & I must "optimize" Firefox. This started ( for many users) 12/30/10. How do I optimize Firefox?

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.
