After a long trek through beta updates, Mozilla has finally released the full version of Firefox 4.

The latest Web browser promises speeds up to six times faster than Firefox 3, and from what I’ve seen, it’s an accurate claim. It also includes the long discussed Do Not Track feature that lets users opt out of behavioral tracking by advertisers.

Of course there are other – and better – ways of avoiding online trackers, (see more here) but Do Not Track is still nice to have.

I toiled with the Firefox 4 beta releases for some time, but always ended reverting back to the previous release.

I had a couple gripes with Firefox 4 beta. It lacked support for most of the extensions I use, particularly many for security and Web development. Thankfully, his has been resolved, which is great given that extensions are among the main draws of Firefox.

All of this aside, however, Firefox 4 has an important update that will help move the Internet as a whole to its next state: great support for HTML5 and CSS3. Basically, it just means that websites will become a lot more fun, with faster load times, and better video support.

Mozilla has a great site to present what HTML5 is capable of (which you’ll need a modern browser to see) – tailored to resemble some 1940s marvel show.

There are a ton of other updates in Firefox 4, which I won’t cover in full here, but check out Mozilla’s site outlining them.

It also has an updated interface for managing extensions, add-ons, and some of the other custom features in Firefox 4.

In a nutshell, there is a whole entourage of new security features, a tabbed interface with site tabs (that resembles Google Chrome), better font support, and the list goes on.

In terms of Web browser use, I use different browsers for different functions. Firefox was always the best when it came to video, media support, and security. I use Safari 5 as my main browser, as it tends to be rather stable; Google Chrome for its translation features and speed; and RockMelt for its social networking features.

That said, however, the latest features in Firefox 4 could replace my use of Chrome and Safari.
