Resetting Pop-Out Location

Using the pop-out on a Win11 multi-screen setup, the Firefox browser on one(1) specific screen results in the pop-out appearing well off screen. It can be moved back into view (it’s annoying).

Have removed the extension and reinstalled, and same screen continues with the problem. (Browser install is controlled at corp.)

Other installed browsers function normally.

I am thinking there must be a config file controlling this somewhere.
If you know where, I’ll thank you for me saving time searching for it.

If you know how to default/reset the pop-ups default location that would be helpful as well. (Maybe best answer.)

TIA

If I understand it correctly, a scaling other than 100% plays a role in it…
