Firefox 6
Mozilla released Firefox 6 a mere two months after the previous version hit the Web. As you can see, that could cause some issues with add-on compatibility.
User Interface
Firefox 6s user interface remains largely unchanged from that of its immediate predecessor.
Highlighting
New tweaks to the browser include reduced startup times and some new highlighting in the address bar.
Mobility
Mozilla is also pushing mobile versions of Firefox in a bid to gain traction with the smartphone users who are driving an increasing amount of Web traffic.
Features
Mozilla hopes that Firefox-specific features such as Tab Groups will give it the competitive verve it needs to battle upstarts such as Google Chrome, while continuing to eat into Internet Explorers market share.
Firefox 7
Even as Mozilla releases Firefox 6, the organization is already placing Firefox 7 in beta.
Rapid Cadence
Mozilla is speeding up its Firefox releases. Firefox 6 arrived a mere two months after Firefox 5, which itself debuted some three months after Firefox 4 entered the marketplace.
Low-Key
Mozilla is keeping the Firefox 6 release a low-key affair, as befitting a browser update thats mostly tweaks to compatibility and performance.
