for whatever reason, whenever I open up firefox it opens up a tiny window that only shows the three buttons for minimizing, closing and resizing windows. I then have to click the Green button (mac osx) to resize it and make it full screen, but it used to open it full screen by default. how do i get it to go back to opening full screen again?

Window sizes and positions are stored in localstore.rdf in the Profile Folder.

Delete localstore.rdf or rename the file to localstore.rdf.sav in the Profile Folder to test if the file is corrupted.

See http://kb.mozillazine.org/Corrupt_localstore.rdf
(caution: do not delete the localstore.rdf file in the Firefox program installation folder)


You can also try to move (delete) the Firefox plist file.

See How .plist files become corrupt and troubleshooting the results

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

Deleting localstore.rdf worked for me, thanks !
