I tested 95.0a1 (Nightly), and opening the hamburger menu (using the steps I outlined above) works now.
Closing it is still partly broken though, as clicking on the menu button doesn't close the menu; I think that is [bug 1694514](https://bugzilla.mozilla.org/show_bug.cgi?id=1694514). For a workaround, clicking outside the menu (and the menu button) does close the menu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940417 Title: On Wayland toolbar menus are sometimes invisible/flickering To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1940417/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
