Mozilla on Monday released beta 3.5 of Firefox, a revamp of the open-source Web browser designed to include better performance, several new Web programming features, and a private browsing mode.

The earlier betas had been numbered 3.1, but Mozilla switched to the version 3.5 name after concluding the changes were more significant than it envisioned earlier. Mozilla has said earlier the fourth beta will the last, with more polished release candidates expected before the final version of Firefox 3.5 is released. You can download Firefox 3.5 beta 4 from CNET Download.com for Windows and Mac. More at; http://news.cnet.com/8301-17939_109-10228665-2.html?tag=newsEditorsPicksArea.0
