On Tuesday, Mozilla released the latest version of Firefox 4 for Android and Maemo smartphones. Firefox 4 now includes support for Firefox Sync, which allows you to sync open tabs, history, bookmarks, passwords, and other data, between your computer and your smartphone. The new Firefox allows for tabbed browsing, add-on installation, and features a new, streamlined look. Mozilla says it will also automatically hide the browser controls when they aren’t in use, which should allow users to view more of the website you’re parked on. There’s also options to save PDFs, share pages, and customize the default search engine. Mozilla says that Firefox 4 is up to 3x faster than the stock Android browser. Firefox 4 for Android is available in the Market now, and the Maemo version can be downloaded here.
