The minefield days are over folks – Firefox 4 reached the beta stages of its development. The mine logo is now gone and bugs (expected as they may be) should no longer be too harmful to the general user experience.
The new Firefox 4 brings a host of new features plus improved performance and responsiveness. HTML5 video with support for the WebM format is what most of the fuss is about but you also get crash protection (which allows you to continue browsing even if a plug-in crashes) and improved security.
The bad news is that most plug-ins are incompatible with Firefox 4 yet so the early upgrade will cost you one of the browser’s key features for a while.
If you are still willing to give it a spin, head for the Mozilla site and download the Firefox 4 beta 1. Just remember to post a comment with your first impressions afterwards.
