firefox plugin information dialog ignores cancel button

[Shawn Walker]

When visiting a site such as www.hardocp.com and using the wheel mouse to
scroll, if one uses the wheel mouse to scroll while the cursor happens to be
over an area where a flash ad is, a prompt comes up information the page
requires a plugin.

Dialog is as such:
"This page contains information of a type (application/x-shockwave-flash) that
can only be viewed with the appropriate Plug-in."

Clicking ok gets rid of the prompt, but clicking cancel does nothing.

Fixed (or doesn't happen for me, anyway) on 1.0RC1
