Hello, I just updated to Thunderbird 130.0b1 on Linux. There is now a white square in the app indicator area, top right on my screen. When I click on it, it show “Quit Thunderbird”. When I have Thunderbird closed, it disappears. How to get rid of this? It’s definitely a bug that it’s a square and don’t do anything except quitting, but even if it was something else, I’d rather not have a Thunderbird app indicator? Thanks :)
