Hi, it shows here you are up to date with latest version 61.
https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox
In you More Systems Details on right of post your useragent shows as being Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.25) Gecko/20111212 Firefox/3.6.25 FBSMTWB
See the above article on how to reset your useragent to the default.
The FBSMTWB on end shows it was made stuck due to the "Fast Browser Search toolbar" extension (FBSMTWB) you had installed at time. This issue was not a problem with Firefox 4.0 and newer.
