Firefox won’t open maximized

It all started after hitting a website that tried to open a pop-up. For some reason, instead of opening a new window, it opened in a tab and resized the main window. I would estimate that the browser window went to about 90% width (full height). Clicking the Maximized button opened it back up to full size.

After that happened, Firefox would not open fully maximized. It would only open to the size that it was changed to after I hit the site (can’t remember which site). I searched through the settings in the Firefox configuration (about:config) but couldn’t find anything to set the size of the window upon startup.

The fix was to go into the Firefox profile directory and delete/rename the localstore.rdf file. Firefox recreates the file when it starts. I don’t know what caused the file to get changed. I do know it has to do with this entry in the RDF file:

width="994" height="705" screenX="0" screenY="0" sizemode="maximized" />

The width and height entries were somehow changed to 950 and 718 (respectively). I deleted the newly created RDF file, edited the two entries in the backup I had made, renamed the backup to localstore.rdf and restarted Firefox. Firefox opens fully maximized each time now.

They sure are trying to take over the IE market, aren’t they?

You can also just right click on the shortcut you use to open firefox and goto properties. There is a run title with a drop down – this needs to say maxmised.
