Hi, I just installed the latest update (I think it's 136.0.2). I guess I skipped some/several versions. Suddenly my main menu isn't workin anymore (clicking it with the mouse, that is) There is some overlay which I can't find out, how to remove. Even the Minimize/Maximize/Close buttons don't have any function. Luckily I can still access the menu via keyboard shortcuts. How can I remove that overlay bar ... or did I catch some malware ?

Do you use any custom userChrome.css file? As a test, enter about:config in the address bar and switch toolkit.legacyUserProfileCustomizations.stylesheets to false.
