Firefox Context-Menu Issues on Ubuntu

[theopfor]

I've never had a problem with this before, so I dunno if this is an update, or just my computer. Whenever I use the context menu (by right clicking), as soon as I am about to select an option, I put the cursor over the box that appears, then it disappears.

Any way I can fix this?

You could try re-installing Firefox as it may have been an update error.
