Wow, before a while I finished and uploaded to the AMO tbNotes 0.2.5. This version brings some new features and repairs some really nasty bugs:

  • note remains attached to the message which is moved to another folder
  • added tabmail button:
  • added support for SeaMonkey (but still not finished)
  • better support for Eudora 8.0.0
  • other minor-bug fixies

You can download it from addons.mozilla.org or directly from this server.
