There is something wonky going on. After I launch firefox which I have done for years, today its started automatically expanding to fill whole screen, no access to any controls, etc. I did try to install software no such luck. See attached screenshot -hmm how do I attach a screenshot.... well if I did you would JUST see the browser filling entire area of my screen (and no making it larger or smaller with mac controls does nothings) you see the top bar for a SPLIT second then it moves up and all you get is this big screen. Thanks - mac here 10. 6.08

I wish I could show you a screenshot. --- you would see I have NO access to the url bar or ANY pull down menus, preference, nothing, just a huge white space with GOOGLE at top the search bar in the middle. weird! Thanks for help!!!! I am afraid I have lost all my bookmarks too (no way to access those either)

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: Command+Shift+F).


1) You can check for problems with the Firefox plist file (org.mozilla.firefox.plist).

Go to "~/Library/Preferences" and remove the plist file for Firefox (org.mozilla.firefox.plist)

2) You can check for problems caused by a corrupted localstore.rdf file.
