Hello, ever since I upgraded MacOS to 15.3.1 and Firefox to 135.0.1 the top menu bar seems to disappear. I do not know which is the culprit, but on MacRumors (https://www.macrumors.com/) you'll find several others with the same experience. My personal observation is that it seems to happen on various Silicon hardware (tried 3) and when '''multiple tabs''' are active. The bug is no showstopper, but to proceed you got to click on the (invisible) menu bar in the upper left. Thanks for reading. ;JOOP!
