I read this thread

https://www.displayfusion.com/Discussions/View/firefox-move-window-to-next-monitor-button-is-missing/?ID=bb095fc1-13f8-4706-bd0b-91656b514f5c

and tried to reply there, but when I hit reply it just went to my account info?

Anyway, I tried what it says in the thread of offset -90 and 10, before I did that I would see the move monitor button if I had 3 or less tabs open with firefox, but after I did it it was still the same. I guess because the tabs cover where the button normally is it disables the button? Is there a way to show the button anyway or move the button to a completely different location? I really want to always have that button showing even if i have many tabs open.
