Firefox doesn't remember the window size
I recently upgraded my monitor and got a larger one. Now when I open FF it opens at a maximized window that doesn't fill the entire screen. So I'm forced to "minimize" it and "re-maximize" it. But when I close it does not remember the true maximized screen size.
I already tried clearing localstore.rdf and by resetting menus under Safe Mode, but neither option worked.

Stop sites resizing your Firefox window: Options->Content tab->Advanced button to the right of Enable JavaScript checkbox
If Firefox is maximized then unmaximize to make the window smaller and close Firefox to save that setting. After restarting you can maximize again. .......... Window sizes and positions are stored in localstore.rdf in the Profile Folder.
Delete localstore.rdf or rename 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.
