I installed an extention that wasn't compaitble with 1.0.3, only 1.0.2... and i didn't realize it until after the fact. It will open up, but nothing works. all the menus are diabled, and you can't even type in the address bar. its almost like its half loaded. Here's what i've done so far, and i'm stumped: redownloaded 1.0.3, overwrote. same problem. removed from add/remove programs redoanladed, installed, same problem removed from add/remove programs regedited, deleted all instances of "firefox" in HKEY_LOCAL_MACHINE -> Software deleted c:\program files\mozilla\firefox\ directory deleted C:\Documents and Settings\Brian\Application Data\Mozilla\Firefox directory (profile info) redownloaded, re-installed same problem. WTF, over? why can't i install it anymore? any ideas where else some corrupt data may be hidden?
