I am using mac OS X 10.11.6. I will not be updating my OS X because newer OS X versions are incompatible with applications I use for my job.

I went to your site offering the latest version of Firefox. While going thru the download process, it asked if I wanted to replace my previous version, so I selected 'yes'.

After continuing, I received an alert saying this version was not compatible with my OS X. I went back to download my older version and cannot find it available anywhere. So now I have no Firefox. Where can I obtain the last version supported by mac OS X 10.11.6?

Firefox ever since 79.0 and later has required macOS 10.12 (ten.twelve) at minimum to run.

https://support.mozilla.org/en-US/kb/firefox-mac-osx-users-esr

The most current you can run on the old EOL macOS 10.9, 10.10, 10.11 is Fx 78.15.0 ESR released back on October 5, 2021.
