TenFourFox 38.4.0 is now available for testing (release notes, downloads, hashes), just in time for you to surf on your iBook G4 while you aim your water cannon loaded with Tabasco sauce at juvenile delinquents craving candy. You know, as you do. Along with fixes for two crashes (most notoriously issue 308) and miscellaneous, this version, as promised, includes complete HTML5 MP3 audio support. To try it out, turn tenfourfox.mp3.enabled to true. If there are no major issues, it will be the default in 38.5.

As always, barring major issues, the browser will be released officially late Monday Pacific time, along with unveiling the new El Spoofistan design for the main page.

In other ecosystem news, I am incredibly delighted to see Tenfourbird 38.3 from our anonymous builder in the land of the Rising Sun, and it works great -- I use it for (appropriately enough) reading news.mozilla.org. Try it. You'll like it.
