Firefox 5.0 Beta Testing on Ubuntu


Really ? Yes ! Firefox 5.0 public Beta & Firefox 6.0 Alpha are now avialable and are ready for testing purposes. We recommend you to keep them upto testing levels as they might annoy you with bugs. In this post we will throw a light on Firefox 5.0 and its key features and updates. It arrived faster than our expectations but its good. We ahve been testing it and so far only 1 bug was found which is potentially not much harmful. We would recommend you to install it only for testing purposes as it may not be good for Production machines.
