Firefox 4 Beta 1 hits Android and Maemo
Firefox Sync, Add-Ons and the Awesome Bar are all included, offering an experience that will be familiar to anyone who uses Firefox on the desktop. Some of those desktop add-ons aren't going to be compatible with Firefox Mobile, though, so don't get too excited.
Although bugs and crashes still happen, FF4 Mobile now includes Electrolysis -- Mozilla's fancy term for separating the rendering and browser interface segments of the app into different processes -- and Layers, which should help with smoothness and stability. Pinch-to-Zoom and a New Tab Screen-like feature called the Awesome Page are also included.
If you're testing Firefox 4 Beta 1 for Mobile, let us know how the experience is going. Will it be your regular browser, or is it still too unstable?
