Firefox 4.0 Beta 1 Released

balster neb writes "Mozilla has released the first Beta of Firefox 4, the next major version of the popular web browser. Apart from the new 'Chromified' tabs-on-top UI, there are many major improvements in performance and HTML5 support. This release also adds support for the new WebM video format. Other changes include faster DOM and CSS performance, improved UI responsiveness, hardware 2D acceleration, experimental WebGL support, and better JavaScript performance (though this beta does not include the new JaegerMonkey JIT engine). More details on the Mozilla blog."

Re:Option to use the old UI?

Just tried it out. You can enable the menu toolbar, and move the tabs back to the original position.. So yes.

Yes, it is possible to revert to original look by disabling "tabs on top". It is also possible to disable/enable menus.

However, I liked tabs on top of the addressbar, feels more intuitive.

Try it safely on your PC with Firefox Portable 4b1

At PortableApps.com, we released the portable package of Firefox 4.0 Beta 1 yesterday soon after 4.0 Beta 1 dropped. It's a great way to test the latest beta without impacting your current Firefox install since it runs self-contained from a single directory. You can even install it to your Desktop or Documents folder.
