Tom, You might want try the latest release version Seamonkey.
The reason 1.4.* version did not work is mostly because the major engine changes made lately. The 1.4.* initial was rework so it would work with TB5 and doesn't work below that on the TB version. I download and tried Seamonkey 2.3 with webmail 1.4.3. and the TB6 version of Hotmail 1.3.5 , Yahoo 1.5.3, and Gmail 0.7.1 and updated the install.rdf to include Seamonkey version 2.3. Probably these won't work below SM 2.2 as the website for note major changes made to SM 2.2. - Last, I went into the SeaMonkey cookie manager and set mail.yahoo.com to "side cannot set cookies". Tom, I didn't need to do this here on version SM 2.3 I imported all my settings in from TB. The webmail extensions all worked except at first I got an RETR error on the Yahoo extension but went anyway. The auto of check didn't for me, probably something I didn't have set right. So looks like the install files needs to updated so that the latest webmail versions of this add-ons will work with SM 2.2 and SM 2.3 other than that I didn't run into any initial problems. Eugene
