Firefox 4.0 Beta 1 Is Out, Download Now

6 Lug/10

The Mozilla developers have released the first beta of the long awaited Firefox 4.0 web browser. Regular readers might know that this version was offered as Firefox 3.7 previously and has now been renamed to Firefox 4.0, a release of the final version is expected at the end of this year.

Firefox 4.0 continues where Firefox 3.7 has left off. It sports a new interface design, something that many veteran Firefox users may have problems adopting with.

Browser tabs are now located on top of the address bar by default with the option to revert the changes so that the interface resembles the old Firefox design.

A second major change is the addition of the Firefox button, which will be shown if the user decides to hide the menu bar in the browser. This option looks similar to the one-button menu option of the Opera web browser.

Firefox 4.0 comes with a new add-ons manager, which is not completely available in the beta release. It is for instance not possible to search for and install add-ons directly from the manager.

The HTML5 capabilities have been improved, with support for web standards such as WebM video and other HMTL5 related features. Firefox 4.0 now scores 189 and 9 bonus points out of 300 in the HTMl5 test, an increase of 50 points and 5 bonus points over Firefox 3.6.4.

Firefox 4 still lacks behind speed wise in most browser benchmarks but it looks like the developer’s have concentrated on interface and feature additions so far.

This version features protection against an attack known as CSS fingerprinting which uses lists of popular websites to determine if a user has visited them in the past.

Interested users can watch a WebM video about the new release, read the release notes, take a look at the first run page or download versions for Mac, Windows and Linux below.
