Mozilla released Firefox 4 beta 1 for Android on October 7, the organization's first mainstream foray into mobile browsing. The software isn't perfect, but it offers several interesting features to distinguish it from rivals such as Opera Mini, Opera Mobile, and the iOS and Android browsers. As with several newer mobile browsers, it's able to show a full version of the Web in miniature.
Sliding the browser window to the right reveals the browser tabs you have open. Each one has a small thumbnail image. When switching to a different tab, you have to be careful not to hit the close box.
One of Firefox's selling points compared to other mobile browsers is the ability to extend its behavior through add-ons. This shows the four installed be default, which provide various search options; the search box to find new add-ons; and recommended add-ons toward the bottom.
