Mozilla is working on a tablet version of the hugely popular Firefox browser which will bring all the Firefox goodness in a tablet environment. Among the things that will make the Firefox browser for tablet something to look forward to is the Awesomebar that is designed to invoke all of your bookmarks or favorite sites right from within the URL bar itself.
Then there are some nice enhancements that will be meted out to the Tabs. Like the Tabs will pile up along the left in landscape mode to provide quick access to them. The same however will get arranged into a menu item at the top of the screen when the tablet orientation in reverted back to portrait mode to allow for more space for the browser to log site contents.
Mozilla has also made their intent of developing an OS for tablet PC and we look forward to that too.
