Firefox 11 Beta, which is now available for download and testing, comes with some big changes, the biggest of which is add-on sync. Firefox Sync, introduced in Firefox 4, allows users to synchronize bookmarks, browsing history, preferences, passwords, and even opened tabs across multiple computers. Users who desired add-on synchronization had to use third party services like Siphon. With Firefox 11, this will be no longer necessary.
The preference and bookmarks migration tool that brings data from Internet Explorer, Opera, and Safari now supports Chrome. In Firefox 11 Beta users will be able to import their favorite bookmarks, history, cookies and profiles from Google Chrome to Firefox.
The silent update process in Firefox has also been improved allowing for seamless browsing experience without any interruption to the regular use of the browser. Until now, Firefox automatically downloads the update but doesn’t install it until the browser is restarted. This results in a delay during the next startup, and the user has to wait more than a couple of seconds.
On Firefox 12 Aurora that will land shortly, Firefox will install the updates while the browser is running. A restart of the browser is still required but Firefox will launch with no delay as the update procedure has already taken place. The update process will be totally seamless with Mozilla getting rid of the Windows UAC prompts that appears before each update. The UAC will prompt you just once, when the first update is downloaded. Subsequent updates of Firefox will no longer require any user interaction.
The new beta also includes support for Google's SPDY protocol, designed as a successor to HTTP, for faster site loading. The Tilt view website visualization tool is now a part of the Page Inspector developer's tool. This 3D visualization is particularly useful when searching through problems in the HTML structure. It’s kind of cool too.
