Ta Da! Firefox 4 Beta 1

Firefox 4 Beta 1 was released by Mozilla. The official release will take place at the end of the year, 2010.

Firefox 4 will be a major upgrade from earlier versions, which will include:

• A redesign of the user interface
• Tabs are at the top -- except in the Mac version
• enhanced HTML5 support
• hardware-accelerated HD video
• WebSockets - low-complexity, low-latency, bi-directional communication system
• enhanced add-on support via Jetpack: a tool that allows developers to create add-ons without needing to have in-depth programming knowledge. Extensions are built using CSS, Javascript and HTML. When they are installed the user will not need to restart the browser.
• Jetpack Gallery - browse the inventions of others in the community - if you build it, they will browse it. :)
