🆕: official SeaMonkey 2.56 Nightly Trunk builds available

This blog post in German languageSince the day before yesterday we have SeaMonkey 2.56 Trunk builds available for testing here — for Linux and WINDOWS and Mac.

Only for testing, you will use those developer-builds on your own risk. I recommend to create a backup of your User Profile before you start testing those builds. My first experience with SeaMonkey 2.56 is that it is too buggy to be used, especially the email client causes lots of crashes.

  1. I already submitted Bug 1418744 Bugzilla: 2.56 missing in VERSION and TM dropdown concerning missing SeaMonkey version in Bugzilla.


  2. It doesn’t work on XP – subsystem version in EXE itself =_= Is it for test release only or they going to drop XP support?


    • I don’t know. You can get help from the public support newsgroup on server “” (or the same as mailing list via ) or on the forum at .


    • The last working version for WinXP is v2.49.x ESR. It’s a shame, but (as always) it’s caused by a Firefox policy.


  3. no win64 nightly builds for SM 2.56a1? only win32 builds are there.


  4. My SeaMonkey 2.56a1 Arch Linux build…..Merry Christmas
