Fx 18.104.22.168 is a Fire Drill (Security) release to address the QuickTime Vulnerability. Currently it has not been pushed out to the ‘GetFirefox‘ page or into the auto updates yet. The GetFirefox page update should be happening later today and the auto-updates are usually within the the next couple days (or some times even the same day). Meanwhile below are links the en-US version of Firefox 22.214.171.124 via Mozilla Download which connects to various download mirrors. Please note: on the download page for the Win32 build, the picture in step 1 shows Firefox Setup 126.96.36.199.exe, but the download is for Firefox Setup 188.8.131.52.exe. Also the Linux build does not have a download page, you will simply be asked if you wish to save the file.
