Vimperator - Muttator Rated 5 out of 5 stars
I use postbox as email client. Postbox is a "spin off" of Thunderbird. Almost the same. Thunderbird addons has to be a bit adapted by the developer to make it available for postbox. Have you ever thought to make muttator available for postbox users? (tnx for the previous answer)This review is for a previous version of the add-on (3.4.1-signed). This user has a previous review of this add-on.
