The wait for the newest edition of the world’s second most popular browser is finally over. Mozilla has released Firefox 4 Beta for preview download available now.
Many of the upgrades are back-end changes designed to improve the lives of Web developers everywhere – a major market for Firefox due to its high ability for customization.
But, as a user, you’ll notice some immediate improvements in your experience. You can now search for and switch to tabs that are already open in the Smart Location Bar. The stop and reload buttons have been combined into a single button for Windows, Mac and Linux. A Bookmarks Button has replaced the Bookmarks Toolbar by default (but can be switched back if you prefer). Crash protection has been added when a crash occurs in Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins. And native support is now included for the video format of the future, HD HTML5 WebM.
