I have the same problem, that the context menu disappears as soon as I move the cursor.
I can also confirm that like guyomel above, if I open and close the preferences menu the problem is temporarily fixed. I expect there are other actions that will also "fix" the issue but I have not yet worked out what they are. At this point I haven't worked out what actually induces the bug, so it's hard to do more testing. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/785195 Title: Right click with mouse opens context menu, but it disappears on moving the cursor Status in “firefox” package in Ubuntu: Confirmed Bug description: Binary package hint: firefox ...
