Firefox 4 Beta 4 lets you sync your data across devices and helps you organize your tabs with Firefox Panorama.
Stay in Sync
Fire fox Sync makes your bookmarks, history, Awesome Bar, passwords, form-fill data and open tabs accessible across multiple computers and mobile devices. Now, with Firefox Sync, you can customize and take your Web experiences with you anywhere, even on your iPhone with Firefox Home.
Firefox Sync encrypts all of your data before sending it to the server and does not track your travels throughout the Web. This means that you never have to compromise your privacy for the convenience of using Firefox Sync.
When downloading or updating to the latest version of the Firefox 4 beta, you will automatically be prompted to create a Firefox Sync account. You can watch the video below for a step-by-step guide.
A Tab Revolution
When tabs were first introduced, the feature changed the way people browse the Web. To continue the tab revolution, the beta now includes Firefox Panorama (formerly Tab Candy) as a new approach to tab management that makes it easy to organize and multi-task while on the Web. If you juggle many open tabs for work, shopping, music, social sites, vacation planning and more, you can easily group and prioritize those tabs any way you want. With one keystroke you can see an overview of all tabs to quickly locate and switch between tabs or groups of tabs.
