Just installed Quantum. After I closed the browser, though, Firefox launches my old version.

There's only 1 version of firefox on my system and it's still the old version.

Hi, yes you appear to be on v52. Please try closing Firefox, then download using another browser from https://www.mozilla.org/en-US/firefox/all/
