The browser won't maximize to fit the entire width of the screen, despite working perfectly fine the previous session.

When the maximize button is hit, the browser window only expands in width to about 3/4 of the monitor. When hovering the arrow over the edge of the browser window, there is no option to manually expand the window to fit the monitor.

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)

Note:
Deleting the file localstore.rdf will reset the customizations of the toolbars to the defaults.
You can rename "localstore.rdf" to "localstore.rdf.sav" to test if that solves it.
Then you can restore the customization by copying "localstore.rdf.sav" to "localstore.rdf" if it didn't work.
