I'm trying to drag one, of several, tabs from a browser (Firefox) on one monitor, to another monitor, and by default with Display Fusion 12.01, the tab bounces back to the first monitor.

I have tried finding the answer myself, and embarassingly I did find it months ago, but now I can't find it again after a windows reinstall. What was the trick for that again?

Hi Keith, Exiting DF makes the issue dissapear back to how things work on any other computer I use that doesn't have DF.

It's frustrating that I know the solution is on this forum or reddit somewhere, but I can't figure out what search words will bring it out.

Debug file attached. After clearing log with L1 enabled, I dragged this forum window to reproduce issue, and exported the log.

Yes either from 3 to 1 or 1 to 3. Those two are side by side.

4 is a drawing pad and 2 is a projector.

Yes, that setting does stop the undesirable browser tab behavior. However, it also turns off a feature that generally is nice, and is one of the reasons I'm using Display Fusion.

So after disabling "Move newly opened application windows to the current monitor", and then re-enabling it, the desired behaviour seems to be working now. Browser tabs can be moved to another monitor and they stay there.

There was never an issue with where the mouse cursor was dropped off. This is also something that I'm certain I had disabled and enabled previously too, but for some reason now the issue seems resolved. Not sure if it was a software glitch, a driver incompatibilty, or what. I'll see if things keep working as desired for the next few weeks.

Unfortunately the issue came back, same as before. If I turn off the setting we discussed, and turn on again, it makes no difference any more, browser tabs still drag to another screen and then bounce back.

I know that when I found the solution to this many months ago, I think it had something to do with making a custom change to Firefox settings within the Display Fusion software, but I just can't find that forum thread again and I can't find a setting like that.

That seems to have been the trick. Can you add that solution to some kind of knowledge base so that others can find this?

Seems like a feature every user would want. Maybe that could be setting, that in the future, is just easily clickable under Display Fusion - Settings - Window Management, or something.

One caveat to this solution and setting, is that if you open up Firefox on a particular monitor, DF will not bring Firefox to that monitor anymore. It would be nice if this setting would only apply to Firefox tabs, and not to the program itself on first opening it.
