@Joseph: Brilliantly spotted. I can reproduce the bug consistently in Firefox like you describe. My Firefox window doesn't need to be maximized - it just has to be near to the right hand side of the screen.
@André: Also brilliantly spotted. This happens on mine as well, including on the desktop, and would explain why I have occasionally noticed this bug outside of Firefox. I think it also explains some of the 'random' link selections in Firefox. -- right click (with button release) might activate popup-menu-item https://bugs.launchpad.net/bugs/187313 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
