Downloaded newer version of firefox, but it isn't supported by my current OS. Need to download my older version of firefox so I can still use firefox.

You don't say which OS version you have. See the link at the bottom of this support article.

Would be helpful if you mentioned what OS/version.

Based on your useragent in More system details, it appears you have the old EOL macOS 10.11

Firefox 79.0 and later requires macOS 10.12 at minimum to run. https://support.mozilla.org/en-US/kb/firefox-mac-osx-users-esr

The old EOL Firefox 78.15.0 ESR is the most current you can run on macOS 10.9 to 10.11
