Firefox 3.1 beta

Smoothly Mozilla beta Firefox 3.1



As they say in Gizmod, the killer feature of the new beta is the 3D interface of the tabs and the included TrasMonkey js engine (which must be manually enabled). In addition, the included Geode, but the long-awaited porn mode is missing.

And by the way, your plugins will not work in beta yet.

Mozilla, in turn, writes:
Firefox 3.1 Beta 1 is based on the Gecko 1.9.1 engine, which has been developed over the last 6 months:

• Gecko meets Web standards even more correctly.
• Added support for CSS 2.1 and CSS 3
• A new tab change window showing their contents (see screenshot)
• Improved control over the Smart Location Bar using special characters to limit your search.
• Support for new technologies, such as video and audio elements, W3C Geolocation API, JavaScript query selectors, web worker threads, SVG transforms, and offline applications.

[upd] To activate TraceMonkey, you need to write about: config and set javascript.options.jit.content to True. In addition, as indicated by coldFlame , you can set javascript.options.jit.chrome = true to speed up the user interface by its precompilation.
