Very Useful Add-on ! Rated 5 out of 5 stars

Can you make it compatible with Thunderbird and SeaMonkey. I like the concept as explained by gadgetman, before that I was skeptical about this add-on and wondering that can there be review for such nifty or useless add-on so I took closer look and saw all 15 reviews and realized the usefulness. Once again please make it compatible to Thunderbird and SeaMonkey.

Thank you,

Thunderbird
