SNUFFYOP  Works as well as tbird 3 and the added features are quite nice. But No plugin support no PGP/GPG Mozilla has done most of the work. why not just setup your code as plug ins to tbird.

SNUFFYOP  I hate to say it but this is really badly written. I've used Yojimbo macJourna caboodle and others. This ware was consitantly corrupting data crashing on import various memory leaks and they do NOT answer their phone.. your lucky to get a response from the ticketing system 4 days after you Uninstall and setup new ware Trust me on this Stay Away. You'll be more sane for the effort.

SNUFFYOP  Great Program works as advertised.. yet after buying the MUpromo on sept 5th.. and then the unlocking on the 8th I think.. I still have not received a license. and haven't gotten a reply to my 4 attempts to get through to support.
