Window is too large for screen, not fixed by f11 or alt/space

more options

When maximized, the view is too big to access the edges to move smaller. When I try to drag the top bar, it jumps to the minimized view rather than letting me reposition the window. The minimized view is only about 2x4 inches. Of course I can make this view larger, but then I lose the choice of two sizes.

There is no problem with changing the size of fonts, etc., just the main view size. The problem is only in Firefox, not other programs.

I tried the resetting Firefox procedure, but that didn't help either.

Oh, wait. Windows does not allow you to resize a truly maximized window, so that fact that it runs from edge to edge without any resizing handles is normal. You only need the above procedure if the window is so large that it blocks the Taskbar or runs off the monitor.

Sometimes the file that stores window dimensions and information about toolbar visibility becomes corrupted. You can rename the file and customize from scratch.

Open your current Firefox settings (AKA Firefox profile) folder using either

  • "3-bar" menu button > "?" button > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

In the first table on the page, click the "Show Folder" button. This should launch a new window listing various files and folders in Windows Explorer.

Leaving that window open, switch back to Firefox and Exit, either:

  • "3-bar" menu button > "power" button
  • (menu bar) File > Exit

Pause while Firefox finishes its cleanup, then rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename that one to localstore.old.

Start Firefox back up again. Do windows display normally again?

If you need to turn the menu bar and/or bookmarks toolbar on/off, you can access the toolbar list from any of these:

  • right-click a blank area of the tab bar, or right-click the "+" button on the tab bar
  • tap the Alt key to activate the classic menu bar, then View > Toolbars
  • on the Customize tab, use the "Show/Hide Toolbar" button (Customize Firefox controls, buttons and toolbars)
