I use multiple monitors, and Firefox switches monitors by itself several times a day (to the main monitor). How to prevent this?

I use Firefox 4, but this happened with Firefox 3 as well.

I have two monitors. I run Firefox maximized on Monitor 2. It switches by itself to Monitor 1 several times a day.

None of my other programs exhibit this behavior.

Windows 7 64-bit.

Thank you!

You can try this:

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.

Thanks very much for this! I will try it as soon as I'm back at work on Monday morning and report back.

Unfortunately, cor-el's suggestion did not work. Firefox still switches monitors by itself. I can't tell what I'm doing when it does this; it appears random.  :(

Try to download "actual multiple monitors" and create a rule for all firefox windows open on necesarry monitor. I'm using this configuration for many programs.. This prog is shareware but with 30-days trial.

I have a similar problem with Firefox 12 (Mac OS X 10.7.3). The main tool bar is on monitor 1 and I want to display browser windows on monitor 2. In previous versions this worked fine. Firefox automatically opened on the last used monitor. Now it will only open on monitor 1, and I have to switch it manually. Other software does not show this behavior. I have tried switching off hardware acceleration, to no avail. Is there anything else I can do?
