Comcast Speedtest not programmed correctly

Comcast Speedtest not programmed correctly

Speedtest asked me to upgrade my browser to the latest version (Firefox) and refused to run. I am on a current version. Firefox has two different browsers' one for home customers; another for businesses. The business version is called Firefox ESR. I just updated it to version 45.9.0 last week (Tuesday) when a patch was issued by Mozilla. It is up-to-date for the version 45 ESR version. My guess is you are only tracking the residential version.


It is not my Flash player. If I alter the user agent to make the speedtest page think my browser is IE 11, everything works fine. The problem is in the code on the Speedtest website (which I have looked at). I've been a programmer for 43 years (since before PCs were even around). I know where the problem is and it's on your end.


Are there any Comcast employees around who can answer this message?
