SeaMonkey 2.53.23 released 31 Dec 2025 3:00 AM (3 months ago)

The SeaMonkey project is proud to present SeaMonkey 2.53.23: The new release of the all-in-one Internet suite is available for free download now!

2.53.23 is an incremental update on the 2.53.x branch and incorporates a number of enhancements, changes and fixes to the application as well as those from the underlying platform code. We have also added many fixes and backports for overall platform stability.

Please be advised that 2.53.21 was the last release with 32-bit versions for Windows and Linux, this version is only 64-bit.

Support for PostMessageOptions for MessagePort has been added to fix issues with the new version of RECAPTCHA.

Support for CSS justify-items legacy has been added to Gecko.

A Linux crash on close issue has been fixed.

If you are using macOS 15.1.x please update to 15.2. Because of a bug in the OS SeaMonkey can not be started via Finder or Dock without workarounds. This applies to older versions too.

We are aware of numerous websites breaking because of only supporting the latest Chrome or Firefox versions. We are trying to address this and progress has been made in a different source code branch but the code is not ready for general distribution yet.

SeaMonkey 2.53.23 is available in 24 languages, for Windows x64, macOS x64 and Linux x64.

Automatic upgrades from previous 2.53.x versions are enabled for this release, but if you have problems with it please download the full installer from the downloads section and install SeaMonkey 2.53.23 manually over the previous version.

For a more complete list of major changes in SeaMonkey 2.53.23, see the What's New in SeaMonkey 2.53.23 section of the Release Notes, which also contains a list of known issues and answers to frequently asked questions.

SeaMonkey 2.53.22 Beta 1 released 22 Sep 2025 4:00 AM (6 months ago)

Our Windows signing key expired in January and the way new keys are distributed totally changed last year. We are currently working on acquiring a new key and integrating the new signing process into our infra, but it will take some time to complete. So until we accomplish this, starting with 2.53.21b1, our Windows releases will be distributed unsigned. If you are concerned about the integrity of the downloads please check the binaries against the checksum files we provide.

2.53.22 will be the first release that does not have 32-bit x86 Windows and Linux versions. We suggest you test the beta to report any regressions which might have crept in so that we can fix them for the final version. The beta should have release quality and the final version can be installed over it.

January 6th, 2025 was a sad day for SeaMonkey and all of us 12 Jan 2025 3:00 AM (last year)

Our friend, SeaMonkey developer and releng William Andrew Gianopoulos, better known as WG9s, passed away unexpectedly on Monday, January 6, 2025.

Visit his obituary for further details and, if you feel so, add a condolence message.

We are still all very sad and will miss him and his cat Bella much. Light a candle for him and remember: No one is really dead unless you stop thinking about him or her and we won't forget him and what he did for sure.

He left a big hole and we will see what we can do about publishing prerelease builds in the future.

Rest in Peace Bill

SeaMonkey and macOS Ventura 6 Nov 2022 3:00 AM (3 years ago)

Attention macOS users! The current SeaMonkey release crashes during startup after upgrading to macOS 13 Ventura. Until we have a fix we advise you not to upgrade your macOS installation to Ventura. No usable crash information is generated and this might take a bit longer than usual to fix. This is not a problem with Monterey 12.6.1 or any lower supported macOS version so might even be an Apple bug.

The problem is tracked in Bug 1797696.

Mercurial Paris Conference 2022 27 Jun 2022 4:00 AM (3 years ago)

If you are a developer then you need some sort of version control system (vcs). While git gets the front seat mostly these days, there are others available. One of them is Mercurial. Guess what, Mozilla is using it and so are we. While we use a git repository for our 2.53 releases and some temporary stuff only, all our development is done using Mercurial. We just think it is really the best and most flexible vcs available.

If you want to check it out or hear more about it, we recommend attending the Mercurial Conference 2022 in Paris.

IRC support channel moved to libera.chat 15 Jun 2021 4:00 AM (4 years ago)

In the last month freenode became a battleground between former admins and management. If you want to know more just use your favorite search engine and you will find all the information you need.

Because of this we planned for some time now to move our irc presence to libera.chat in the next few weeks. Unfortunately freenode forced us today to do this on short notice. All registered nicknames were removed and channels basically left without operators and owners. This is not acceptable and at this point in time we no longer have any interest in having a presence there.

Effective immediately all official SeaMonkey support on freenode has ended. We are now on libera chat. If you are a cZ user we suggest using 2.53.8b1. Full support for it has been added to the bundled chatZilla and you don't need to set up the libera network manually. There were no problems reported against the beta and the final 2.53.8 version will be spun soon.

You can access the SeaMonkey irc channel with the following link SeaMonkey irc libera chat channel. We are looking forward to see you there. Full logging for the channel will be set up soon.

Change of support options 16 May 2021 4:00 AM (4 years ago)

Hi folks hope you are all well and healthy. We want to announce a change in our support groups. Mozilla will turn off the nntp lights and so the newgroups mozilla.support.seamonkey and mozilla.dev.apps.seamonkey will go away soon. These were actually not real nntp groups but mailing lists mixed in with nntp. The mailing lists have been moved to google groups. The nntp servers will be archived and then switched off. We do not have a final date for this yet. SeaMonkey is also a nntp client so as a replacement a new nntp group alt.comp.software.seamonkey has been created.

As usual we would like to remind everyone that we also have release notes which contain a list of known problems and, if there are any, also solutions for them. Also keep in mind that the SeaMonkey council mailing address is not a help line. If you are unable to solve a problem using the normal support options please file a bug in Bugzilla. Especially problems with specific websites should also be discussed in the support groups first. We are working on enhancing web compatibility but many sites also just do incorrect browser detection and present a flawed site.

SeaMonkey and the future 4 Sep 2019 4:00 AM (6 years ago)

Wow! A new release and two news items together. What is cooking?

With the SeaMonkey 2.49.5 release the 2.49.x line comes to an end. Unless a catastrophic bug is discovered 2.49.5 will be the last ESR 52 based version. Backporting security fixes and at the same time working on the next, already overdue, major release is not possible with the few remaining developers.

Plans are to do further interim 2.53 versions based on a much enhanced Gecko 56 base while working on bringing you the next ESR 60 based 2.57 version. After 2.57 we will decide about the future. The current Mozilla Gecko codebase has seen a flow of constant major changes and api removals in the last 2 years and is no longer really usable for our needs. By the end of the year the SeaMonkey project is expected to be completely independent of Mozilla. We will see how this pans out but we are doing our best and already have a new infrastructure in place where we do builds and website hosting.

We would also like to remind everyone again that this a community project independent of Mozilla. So if you want to continue seeing future SeaMonkey releases please help by either donating money or even better help out with development. We are still committed and hope you are too.

Help squashing bugs in mail and news 3 Apr 2019 4:00 AM (7 years ago)

Our Thunderbird friends ask for help squashing bugs. If you have some spare time help them and also us because SeaMonkey and Thunderbird use a shared codebase for mail and news.

Some Details from the announcement:

We are grateful to have a very active set of users who generate a lot of bug reports and we are requesting your help in sorting them, an activity called bug triage. We’re holding “Bug Days” on (all day, EU and US timezones) and (EU and US timezones until 4pm EDT). During these bug days we will log on and work as a community to triage as many bugs as possible. With several of us working at the same time we can help each other in real time – answering questions, sharing ideas ideas, and enjoying being with like-minded people.

No coding or special skills are required, and you don’t need to be an expert or long term user of Thunderbird. Some things you’ll be doing if you participate:

• Help other users by checking their bug reports to see if you can reproduce the behavior of their reported problem.
• Get advice about your own bug report(s).
• Learn the basics about Thunderbird troubleshooting and how to contribute.

But we hope you’ll join us on the 8th or the 13th via #tb-qa on Mozilla’s IRC so that we can put these bugs in their place which helps make Thunderbird even better. If you have any questions feel free to email Ryan.

Visit the Thunderbird Blog to see the full announcement.

Today is "I love Free Software Day" 14 Feb 2019 3:00 AM (7 years ago)

And if you are wondering when the next release will be out, then read about the progress we are making in our SeaMonkey Project Blog.
