Before I fill out a bug report and set up an account with Launchpad I thought I'd post the problem first.

When I use the mouse to copy a link and then right click the drop down opens but as soon as I attempt to use the drop down with the mouse the drop down crashes.

All of the drop down windows in Mozilla Firefox in Bookmarks I get the same thing. When I right click on the Bookmarks tab the drop down appears but upon trying to use the mouse pointer to scroll down the drop down box; the drop down menu crashes.

This has been going on for a while now. I've had to use the up, down, right and left arrow keys to copy and paste anything. It's starting to become annoying and makes it very difficult to post or e-mail.
