This is a biggie! Firefox 4.0 beta 1 has been released. And you know what, it’s packed with a lot of features. Firefox recently released the 3.7 alpha version. But today, the Firefox v4.0 promises to provide us with some new features like a new Tab location, Enhanced HTML 5 support and WebM support. What are you waiting for? Go download the Firefox 4.0 beta 1 now. I just installed the 4.0 now. Will keep you posted if there are some bugs or any new undiscovered features.
And I must admit, It has a very enhanced Cache system and the speed of opening websites are damn good when compared to previous version
One notable feature I saw was the Aero feature integration into firefox for tabs like IE 8 does with Windows 7. I’ve been waiting for this for a really long time! 
Also, Im not seeing any plugin incompatibility with the new version of Firefox 4.0. This version of Firefox will definitely create some record.
Bug No.1:
The first bug I saw was that there is no Close, Minimize and Maximize buttons on the browser! 
.
Update: This bug seems to affect only me! Wondering why this is happening!
