After I submitted the question, I found the instructions for reseting my user agent here https://support.mozilla.com/en-US/kb/Websites%20or%20add-ons%20incorrectly%20report%20incompatible%20browser. This solved the problem. Thank anyway! :)

For the record, you have a general.useragent.override setting showing in your More system details list. 

general.useragent.override: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.15) Gecko/2009101601 Firefox/3.0.15

Using that pref to change the user agent (and forgetting about it) can cause such issues. You may have had an extension installed to spoof the user agent.
