User sg9s offers several current SeaMonkey builds from latest Source:  SeaMonkey 2.49  | SeaMonkey 2.53  | SeaMonkey 2.57 | SeaMonkey trunk, all for WINDOWS and Linux.

I am currently doing some tests with unzipped installer of unofficial (by wg9s) en-US SeaMonkey 2.53 (NT 6.1; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0 Build 20180902143701 (Default Classic Theme, German Language Pack active) on German WIN7 64bit.

SeaMonkey add-ons will be moved to

I received an e-mail from “The Thunderbird & Add-ons teams”:

” … Starting on July 12th, SeaMonkey add-ons will be listed on, which is the new home for Thunderbird and SeaMonkey add-ons. This new site is being run by the Thunderbird Council. If the add-ons also support Firefox or Firefox for Android, they will remain listed on AMO. Otherwise, their listings will be removed, and their URLs will redirect to the new site. Similarly, update URLs will be redirected, so all of your users will continue to receive automatic updates on the new site if you upload new versions to it. Your developer account will also be ported, so you should be able to log in and manage your listing.

If you come across any issues or need any support during this transition, please leave a comment on this Discourse thread.

If you don’t wish to be notified about these add-ons anymore, please disable the listing pages on the new site, and the old one, if needed”

I tested the new site, currently (as expected) still “503 Service Temporarily Unavailable”

May be we will have to adapt SeaMonkey Help, website, wiki, …. All that should be handled via Bugzilla as soon as the new site will be running.

UI completely broken in 2.56a1 Trunk ⚠️️

I used a newly created test profile

So (browser-) UI looks with official en-US SeaMonkey 2.56a1 (NT 6.1; WOW64; rv:59.0) Gecko/20100101 Firefox/59.0 Build 20180119000058 SourceStamp=ae43fcf7b9ee449f0f0a573d10c93421dbe645bf || ID={92650c4d-4b8e-4d2a-b7eb-24ecf4f6b63a} (Default Classic Theme) on German WIN7 64bit.

May be developers should give some advice in which area and for which builds user-bugreports currently can be useful? I doubt that testing with current (WIN) trunk can yield any benefit 🤔.
