Mozilla have released the final version of FireFox 26 for all the three operating systems, on to their FTP servers.
Besides improving page load times, the major changes in this version are, the inclusion of Support for MP3 decoding on Windows XP and Support for H.264 on Linux (for gstreamer plug-ins)
Here is the full official change-log for FireFox 26:
