How to open firefox maximized?

Whenever i open firefox, it *always* makes itself windowed, but with the dimensions of my screen, meaning it's overlapping under windows' task bar, which is really annoying: I always have to manually maximize firefox after i started it.

  • If i right click on firefox's icon and go to properties > Shortcut > Run and set to "Maximized", nothing is changed.
  • When I maximize firefox manually, close it, and reopen it, i see briefly firefox maximized, then it quickly changes to windowed mode again.
  • I checked in the options and failed to see anything that could help.
  • Out of despair, i even tried to blindly search in the variables available in about:config, without luck.
  • I tried this on 2 different systems, both with windows 7 x64 installed and 8GB of RAM, without luck.

My system:

OS: windows 7 home premium x64 RAM: 8GB CPU: i7-920

Hey again, that other solution didn't work (be it manually or via safe-mode), but in finally managed to find where the problem came from: the addon "DeveloperCompanion 1.0b1rc41" , which i've been using to debug Zend based websites. When i disabled it, the problem was gone!

Thanks for the help!
