I see where others have posed this same question however there are no answers given. What is the answer?

You appear to be using Firefox 44.0

So either you are really using Firefox 44.0 and need to update. https://support.mozilla.org/en-US/kb/update-firefox-latest-version

Or if you have Firefox 48 then perhaps your useragent in stuck at Firefox 44.0 https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox
