Here are some new Features of FireFox 4 Beta
Firefox Panorama
Firefox Panorama, formerly known as Tab Candy, is a tab-management tool. In its former guise, it was an add-on developed for Firefox 3.5, though from now on it will be a standard feature. You can create groups of tabs – those that relate to work, for example, or an interest or hobby – and keep them separate from other tabs you might have open. At the touch of a button, you can get an overview of each of the open pages in your tab group – much like Opera’s Speed Dial feature. You can also flick between groups easily and create custom names for each one.
