I really like this idea behind this add-on!
Unfortunately, it wipes out the status? bar at the bottom of the Thunderbird window that displays the real url when you mouse over a link. (The status? bar also shows progress when downloading messages, compacting folders, etc.)
Because the url disclosure is my main means for checking urls, I'm giving version 0.9.0.6 a thumbs down.
Please fix this feature/bug! I'd really like to use this one, especially given the new birage of phishing spam!
By the way, this add-on takes 25 seconds (on an unloaded Fedora Linux 15) to create the warning popup.
