Firefox opens on the wrong monitor

I always use Firefox on my secondary monitor. When I close and re-start Firefox, it opens on the primary monitor. All other applications don't show this behavior.

It seems Firefox is forcing itself to the primary monitor. Default Windows behavior is for an application not to move itself around, and then window position and monitor is remembered by Windows.

Not related to your problem but some of your Firefox Plugins are out-dated

  • Update All your Firefox Plugins -> https://www.mozilla.org/en-US/plugincheck/
  • NOTE: When Downloading Plugins Update setup files, Remove Checkmark from Downloading other Optional Softwares with your Plugins (e.g. Toolbars, McAfee, Google Chrome, etc.)

I've got some more information to reproduce the problem. Once firefox is neither maximized nor minimized, the position is remembered. Once maximized, the monitor is not remembered, but maximized-state is remembered.

To reproduce:

  1. Start Firefox and make sure it starts maximized on monitor 1
  2. While still maximized, drag it to the top edge of monitor 2, so it remains maximized, but now on monitor 2
  3. Restart Firefox -> Result: Firefox starts on monitor 1 instead of 2.

(there may be other methods of reproducing this problem, but this is what I did)

Workaround:

  1. Restore the Firefox window
  2. Restart Firefox (not sure if this is necessary)
  3. Maximize at will

I'd call it a bug.

If Firefox is maximized then make the window smaller and drag that window over to the correct monitor and close Firefox to save that setting. After restarting you can maximize again.

Check and tell if its working.
