Mozilla announced the launch of Firefox 29, which it calls its most customizable Firefox ever.

It includes a new design, a customization mode, a new Firefox menu, new bookmarks, a new add-on manager, and enhanced sync powered by Firefox Accounts.

“The first thing you’ll notice in Firefox is the beautiful new design that makes it easy to focus on your Web content,” says Mozilla. “The tabs are sleek and smooth to help you navigate the Web faster. It’s easy to see what tab you’re currently visiting and the other tabs fade into the background to be less of a distraction when you’re not using them.”

“The Firefox menu has moved to the right corner of the toolbar and puts all your browser controls in one place,” it says. “The menu includes a ‘Customize’ tool that transforms Firefox into a powerful customization mode where you can add or move any feature, service or add-on. This level of Firefox customization puts you in control of your Web experience and is unmatched by any other browser.”

The new Firefox Sync gives users access to the Awesome Bar browsing history, as well as saved passwords, bookmarks, open tabs, and form data across computers and Android devices.

Mozilla also lists supported web platform and developer tools including WebRTC, WebAPIs, asm.js and Emscripten, Web Audeio API, CSS Flexbox, App Manager, and Extension APIs.
