Over two months after launching Firefox 10, and backing it up two two security updates (10.0.1 and 10.0.2), Mozilla is almost ready with the stable version of Firefox 11, which it is reportedly launching later today. Mozilla posted what was supposedly Firefox 11 stable on its FTP, before redacting it, citing that the build is not actually stable, and that QA was still on.

Firefox 11 will introduce several new features, including performance improvements. To begin with, Firefox 11 supports the SPDY protocol, all pages are loaded on SSL with SPDY, which is both faster and more secure. Firefox' bookmarks and preferences migration assistant will now support Google Chrome, letting users migrate from Chrome to Firefox. Firefox Sync will now also synchronize addons between sync'd PCs. Lastly, Firefox 11 is said to include more feature-rich developer tools. The Android version of Firefox 11 will ship with Adobe Flash, for Android 2.3 and earlier.
