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.
The software emerges amid what's become a fiercely competitive browser market. Microsoft has released a significant new version, Internet Explorer 8, while Google has entered the market with Chrome and Apple is trying to secure a Windows foothold for its Safari browser. Firefox holds second place in market share to IE.
There are a number of known problems with Gmail and with AVG SafeSearch v8.0 on Windows, and as usual, many of those extensions that are so popular on Firefox could break. For details, check the release notes.
