When I swipe my cursor down from the tabs to the main screen, the alt-text link preview box from the bookmarks-toolbar links gets stuck. This usually happens immediately after I switch tabs and move the cursor down quickly. I've attempted to turn off all my addons and themes and remove my pinned tabs, and it didn't help. It occurs on my very modern laptop. It is very very annoying to see a yellow link box hovering, stuck, while you're trying to concentrate on the main screen. This does ''not'' happen on my desktop PC. I will always be loyal to Firefox, but this, and other issues posted separately, had me considering changing browser for the first time ''ever''. It was frightening.
