If you're having trouble resizing an oversized window:

  • Enable JavaScript. (Firefox: Tools -> Options -> Content -> Enable JavaScript; Mozilla Suite: Edit -> Preferences -> Advanced -> Scripts & Plug-ins -> Enable JavaScript for -> Navigator)
  • Make sure scripts can resize windows. (Firefox: Tools -> Options -> Content -> Advanced JavaScript settings. Mozilla Suite: Edit -> Preferences -> Advanced -> Scripts & Plug-ins).
  • Type: javascript:top.resizeTo(screen.width*0.8,screen.height*0.8);self.moveTo(0,0); into the Location Bar and press Enter.

Other methods of resizing windows:

  • Drag the edges of the windows to resize, drag window by title bar to move
  • On Windows use Alt+SpaceBar to move and resize window, especially if the title bar is not accessible because the window is too high.

Combining the two above topics

  • Create a Bookmarklet with a keyword of "1024:"
  • Invoke the bookmark by typing 1024: into the location bar
  • The window will fill up the available height with a width of 1024 pixels, next steps allow you to move the window left or right by dragging the title bar, you could also resize by dragging borders. Another way of moving left and right without moving up and down accidentally.
    1. "Alt+SpaceBar" > "M" (Move)
    2. use left and right arrows keys to move left or right, use "Esc" to en

If after following these steps, new windows still start up too big, you may have a corrupt localstore.rdf.

Some causes leading to problems of oversized Windows:

  • Extensions: Babylon Toolbar 1.1.8,  vshare 1.21
  • Zooming and them moving the window.

Causes external to Firefox

With larger screens and monitors and accessibility features the screen resolution or DPI may have been changed for a display screen, and this would affect all applications using a display (screen/monitor).  100% is normal, see if settings have been changed.

Windows 7

Display settings default is 100% but may have been inadvertently set to 125%, 150%, or 200%. See Change your screen resolution. You generally want to go with the recommended settings for your laptop or monitor.

  1. Control Panel (to get to Control Panel\All Control Panel Items\Display\ )
  2. Screen Resolution -- see link "Make text and other items larger or smaller")
  3. Display -- "Smaller 100% (default)" (custom DPI sizes on the left panel allow other sizes than shown)
