The address bar in Firefox used to do a google search when I typed something. So if I typed 'Blue wallpaper' a search was conducted. Now, I get a screen saying 'File not found' ? I tried going to the about:config part and putting the google link in the keyword URL, but it only lasts about 5 minutes before returning to the 'File not found' screen. I want it to always search, but how? And I've also checked the 'true or false' thing on the keyword search part and it's always set on true but the google search still doesn't work!
