I can confirm that the repro steps posted by gw0 work for me here on 8.10 / i386 with Firefox 3.0.7.
In case it's not obvious, a scenario where this would happen in reality is when you right click and then discard the menu by left-clicking outside of it. The next time you right-click on something, it will trigger the repro steps if the new thing you clicked on is within the area where the "ghost" menu was. This would frequently happen when you attempt to right click on a link in order to open it in a new tab, but miss it at first, and try again. Especially on cluttered pages with small fonts, this could happen easily, as well as if your motoric skills with the mouse are not stellar (which is likely to be the case especially for new users, who ought to be specially shielded from erratic and confusing behavior). -- [MASTER] right click (with button release) might activate random 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
