Mozilla continues to follow the same strategy as Google does with Chrome, creating different development channels to release early versions of their browser as soon as they’re available and keep the final one updated as often as possible.
Note that Firefox 10 is strictly a beta release meaning no guarantees can be made about stability or functionality or compatibility with add-ons. There are several changes in Firefox 10. One notable absence is the disappearance of the button to go to the next page. From now on, this option will be hidden and will not appear until the button is displayed on a previous page.
There are also improvements to CSS3 support, 3D transformations and WebGL anti-aliasing. In addition, there's a new full-screen API for creating web applications that run in full screen.
The interface is pretty much the same as Firefox 9, with a minimalist toolbar and there's still no way of removing elements that you may not want such as Java and .Net Framework. The major downside for most users however is that some plug-ins or add-ons won't work with Firefox 10 yet - so if you have a lot installed, prepare to be disappointed.
Firefox 10 Beta has some useful enhancements for fans of the browser,
