Improvements over Firefox 1.0.x versions include an automated update system to streamline product upgrades, faster Back and Forward navigation, a feature for clearing private browsing data, drag-and-drop reordering of browser tabs, a redesigned Options/Preferences window and better popup blocking. Web standards support is also improved, with support for Scalable Vector Graphics, JavaScript 1.6 and more CSS. Accessibility is also better (including new DHTML accessibility features), security has also been enhanced. Firefox's Extension System has been redesigned to make extension upgrades cleaner (nothing left behind from previous versions).
This DOES break some current extensions, so if you use extensions, CHECK FOR UPDATES. Extension authors are aware of this, and many extensions have already been updated. By the time of the final 1.5 release, all extensions should be updated.
