Yesterday after updating the personas I noticed that some buttons in my Google toolbar were missing. I tried to sign in again to see if that would fix it. I couldn't get Google to communicate with the server to find my set up. I went to the add-ons to try to delete Google toolbar but I got a script error that said a script was running and I could never get it let me in to add-ons. I did a roll back in win7 but it did not fix the problem. today I can't even get Firefox to start. I'd certainly like to fix this without messing up all my settings if possible.
