A few times a day I come across this problem where I can’t click the x on the tab and close it. It’s been happening for a few weeks. I can right click and click close but otherwise I have to completely close Firefox and reopen it for it to properly work again. I’m using version 139.0.4 (not Flatpak) on Fedora 42 with GNOME. Anyone else having this issue?
I am also running 139.0.4 non-flatpak on Fedora 24 with KDE and experiencing the same.
Unfortunately, it was happening often enough to make me change browsers until it gets sorted out.
Same here Fedora 42 GNOME 48. I also have 3 monitors and it only happens on Monitor 1 which is not my primary display (1 left ,3 primary, 2 right).
