Using Mac OS X 10.9.2. Firefox worked fine before the last update. It does not matter if I am in full screen or a window. The bottom section of the window is consistently off the edge of the screen.

Hi tremph, Thank you for your question. You can change the window size with a few cool add ons Automatic Window Resizer and Firesizer.

  1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
  2. Click I'll be careful, I promise! to continue to the about:config page.
  3. What is the feature http://kb.mozillazine.org/Browser.display.screen_resolution
