Using 3 monitors, Firefox opens on left, how to get it to open in center monitor (IE opens in center)?

I have a 3 monitor set up and EVERYTHING opens in the center monitor (except some flight sims which are set to open in Wide mode - using all 3 monitors). If I want something on one side or the other I drag it there. Internet Explorer opens in the center and Firefox used to open in the center, but now it opens on the left and I can't stop it or change it. The only way I can get it in the center is to start to drag it, at which time it pops open and full expands to cover all 3 monitors, and then I can click on the little square in the upper right corner and it reduces itself to just the center screen. I have no idea why this has changed and I can't find any settings that might have affected it. So, any suggestions would be greatly appreciated. thank you.

Well, you can change your primary monitor and see if that helps.

Hello Sajjad,

Thank you for taking the time to help. Unfortunately, I believe if I changed my monitor configuration, all of my other programs would be out of sync and only Firefox would open in the center monitor.

I'm still guessing there's some kind of setting (maybe something I even unknowingly changed) that is "telling" Firefox to now open in my left monitor. It's strange, but I feel there is a really, really simple answer somewhere.

This is a O/S video driver operation the Browser can't control where it opens.

Hi WestEnd

Thank you, but I still don't understand (I'm not a tech person). I certainly did not change anything in the O/S (I wouldn't know how). Firefox was always opening in the center monitor, just like all of my other programs (including the IE browser). Suddenly, it just started opening in the left monitor. If it's an O/S problem vs. a Firefox problem, I guess that may be beyond what anyone here can help me with, but I'd sure like some suggestions.

Thank you.
