I downloaded and installed Firefox 1.5 Beta 1 today because there’s nothing I love better than the beta version of a Web browser. You can read about all the cool new features in the release notes, and what the browser offers developers in an article by Simon Willison, but what you really want to do is install it and try using the back and forward buttons. I had no complaints about the back button previously, but it is now instantaneous. I’m eager to see how much better the popup blocking is as well – advertisers seem to have caught up wtih the current release of Firefox to a certain degree.
