User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.43 Safari/537.31 Steps to reproduce: Update firefox to version 20.0 Actual results: The adresse bar and search bar are not working anymore. The search engine list is empty and I cannot add or restore. Expected results: The adresse and the search bar should have worked.

I found the source of the problem. It's because my firefox profil is on a network drive. I created a new profil (firefox.exe -P) and saved it on my local drive and it solve the issue. But I lost all my settings/add-ons/etc...
