The Mozilla team have released the first beta of Firefox 3.
Although not complete this version has had a lot of optimisation to make it quicker and easier to use. The rendering engine has been changed to the Cairo engine which is powering many open sourced projects.
Two features added on the location bar are a website identity tool so you can find out about the website you are visiting and a one click bookmark feature by clicking a little star with optional tool to fill in the location and organise the page bookmarked.
Other changes are better security management and notification, native web forms which conform to the operating system being used and Vista support.
