Firefox 4 is still in beta, but it’s already building up nicely!  The list of new features is awesome!  Let jump right into what it has and can do… It allows you to modify a tab into an app tab — which means right click on a tab that you visit often and make it into an app tab will forever make the the tab sticky and will not go away, but you have the option to demote an app tab into a normal tab which will go away.  This is an awesome feature, because it saves you time from reopening the frequent tab that you will visit often. It allows you to organize tabs!  How?  Hundred of opened tabs won’t confuse you anymore…
