It won't allow me to upgrade, I can download and install as if there is no issue, but once I actually get back on, it's still the same old version.

Chances are your user agent is just wrong. See below to check:

  • Type about:config in the URL bar and hit Enter
  • If you see the warning, you can confirm that you want to access that page.
  • Filter = general.useragent.
  • Right-click the preferences that are bold, one line at a time, and select Reset.
  • Then restart Firefox
