SeaMonkey 2.5 Beta 2 — Introduces new features

SeaMonkey 2.5 Beta 2 is available for free download now in 24 languages and makes a list of new functionality available to a wider testing audience for the first time. Please note that this pre-release version is still intended for testers only and might still show some problems in everyday use. As always, we appreciate any feedback you may have and encourage users to help us by filing bugs.
This version is built on top of Gecko 8 and features the following new improvements:

  • Users now have more control over their add-ons. Upon upgrade, activation of third-party add-ons needs to be confirmed explicitly.
  • Improvements to HTML5 media elements and added support for newmedia APIs to improve the overall performance of video and audio
  • Additional support for HTML5 technologies, including the crossorigin attribute and insertAdjacentHTML
  • Updates to WebSockets
  • Support for CORS for WebGL cross-domain textures
  • Hyphenation is now supported in many more languages
  • Fixed several stability issues

The changes page lists a more detailed overview of new features and fixes relative to our last stable release, SeaMonkey 2.4.1.
We welcome any and all discussions on this beta on our newsgroups, or you can even file a bug if you find one. Be sure to check our Known Issues prior to filing bugs.
SeaMonkey 2.5 Beta 2 is available for free download on the SeaMonkey website. Once you have downloaded and installed this release, we’d like to encourage you to get involved in discussing and reporting problems as well as further improving the product.
Thanks for testing and helping us to make SeaMonkey even better!
Thank You,
~Justin Wood (Callek), SeaMonkey Release Engineer

Attention: Users on older SeaMonkey Versions may be unable to update.

For those of you who are reading this and on a SeaMonkey version 2.1 through 2.3.0 you will be unable to currently update your version of SeaMonkey through automated means. (SeaMonkey 2.0.x did not have this update security measure, so is unaffected)
Our secure certificate for updates, used to protect you, our users, from fraud and issues with the update had to be changed. The one we had expired and we were unable to renew it with the same information we baked into SeaMonkey by default.
We fixed this issue in our version 2.3.1, so if you have that version or newer you will not be affected. And no need to worry.
You can manually install a new version from our website at Or apply our hotfix
I have created a hotfix addon you can install into your SeaMonkey to once again update to a newer version of SeaMonkey via our internal update mechanics. This hotfix currently requires a restart of SeaMonkey, though I do plan to update it in the future to be a “restartless” addon for the versions I am able to.
This is different than a confusing error that gets reported in versions from 2.3.1 and newer that indicates the update server is a wrong certificate. This error is reported whenever we check against our builtin list, and of course it finds the first one we have listed as incorrect and reports it. The next cert in line is found to be ok. So this error ends up being a false positive.
