If you're having trouble resizing an oversized window:
(Using JavaSript to resize windows is forbidden in Firefox 7.0.1 and up [1]);

  • 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:

  • "F11" toggles in/out of Full Screen mode, make sure you are not in Full Screen mode in order to resize a window
  • Drag the edges of the window 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. Move allows you move window. Size (resize) allows you to resize in a vertical or a horizontal direction but not at the same time. You can use the mouse or the cursor keys with move or size.
  • (Windows 7) use WinKey+right-cursor-key to move Window to right side of screen -- works across multiple monitors, and window can be resized afterwards by moving edges of the window. May also be used if Window gets lost on a monitor no longer connected -- use shortcut until window appears in position on current screen.
  • On Mac: see "How to resize a window on your Mac’s screen that’s too big to drag" (MacYourself)

Combining the two above topics
(Using JavaSript to resize windows is forbidden in Firefox 7.0.1 and up [2]);

  • Create a Bookmarklet with a keyword of "1024:"
    javascript:self.resizeTo(1024,screen.availHeight);self.moveTo(screen.availWidth-1024,0);
  • 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. (Windows) "Alt+SpaceBar" > "M" (Move)
    2. (Windows) use left and right cursor keys to move window left or right, use "Esc" to end

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 then moving the window.
  • Switching display between monitors
  • Dragging window between monitors

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)

JavaScript no longer allowed to resize windows

Resizing with JavaScript has been made almost impossible beginning with Firefox 7.0.1 due to Bug 565541 – Web sites shouldn't be allowed to resize main window, which essentially renders the help provided on this page as useless and leaves users with problems without a simple circumvention to regain control so they can work including to work on fixing problems.

Overriding is convoluted because you must make a configuration change (about:config) to change services.sync.prefs.sync.dom.disable_window_move_resize to false. You must invoke the JavaScript directly from a bookmark while in "about:config" as the active tab, and you can not invoke the bookmarklet as a keyword shortcut from the location bar.
