Lost previous Firefox, cannot load replacement

more options

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.

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.
