Can't use it for now, as it does not (yet) support Firefox 4.0.1.

Some years ago I downloaded a similar add-on, which claimed to usable for both Firefox (don't remember which version) and Thunderbird. As far as I remember, I installed it in Firefox, where it did not seem te do anything, but though installed in FF, it worked in Thunderbird. Strange behaviour. I hope this one will be better, especially when it is available for FF 4.0.1.
