Thank you Eyal!... Rated 5 out of 5 stars
Thank you for rewriting this extension Eyal so that all may enjoy the simplicity it affords us, and the time it saves keeping our email folders clean and uncluttered because of excess duplicates. This is a can't-live-without ext'n! A must have for anyone with any amount of emails.
For those of you who don't realize what Eyal has done here, and the gift given us, read the mozdev page http://removedupes.mozdev.org/ .
