Mozilla Firefox has undergone an enormous rebirth over the past two years. Since Firefox 4 debuted in March 2011, the browser has been hell-bent on improvements. These have come in large part on the rapid-release cycle, which sees a new version of Firefox every six weeks. Many people like them, but a vocal minority has pooh-poohed the increase in version numbers. That's hardly a legitimate complaint in a world where mobile apps also update silently and effectively, but the transition for Firefox hasn't been an easy one.
As you can see, Firefox is on version 15 at the time of this review. As a point of comparison, Chrome is currently on version 21 even though it only launched in 2008. The benefit, of course, is a browser that is safer and sleeker, with fewer problems because bugs get fixed on a regular basis.
The Firefox that you can download now is in the same speed category as its competition; offers many similar features (stronger in some areas and slightly weaker in others); includes broad, cross-platform support for hardware acceleration and other "future Web" tech and standards; and is a must-have for Android users (download for Android).
Firefox 15's big claim to fame is locking down memory leaks caused by add-ons, long browsing sessions, and heavy tab usage. The company released data showing huge gains in recovering memory with 150 tabs open, so you're likely to see big gains with only 50 tabs.
On the performance side, Firefox 15 now has Google's SPDY protocol on by default. That means that Web sites that support it, such as Google.com and Twitter.com, will load faster and safer. SPDY is safer because it forces SSL encryption for all connections.
It's important to point out that there are four versions of Firefox available at the moment, and this review only addresses the stable branch, intended for general use. Firefox's other channels -- Firefox beta (download for Windows | Mac | Linux); Firefox Aurora, analogous to Google Chrome's dev channel (download Aurora for Windows | Mac | Linux); and the bleeding-edge, updated-nightly Firefox Minefield (download for all versions) -- are respectively progressively less stable versions of the browser, and aimed at developers.
