Although not officially launched, the stable version for Firefox 15 is ready for download, as Mozilla has completed the code merging from beta and Aurora branches.
The release notes for the new stable version of the browser are not final yet, but the document for the beta announces support for SPDY networking protocol version 3 and WebGL enhancements, including compressed textures for better performance.
Also included is native preliminary support for PDF, which means you can use the browser to open Adobe’s portable documents. This is already available in Google Chrome
Another improvement consists in the fact that Mozilla managed to fix plenty of memory leaks caused by add-ons. For some users this should translate into a faster and more stable browser, more so for those that work with multiple add-ons and keep Firefox running for longer periods of time between restarts.
