I am running El Capitan and need Firefox 78. I went to a site offering 78 as a download, and version 91.5 came down. Site offering 78esr, same thing. Went to https://ftp.mozilla.org/pub/firefox/releases/ and was unable to figure out how to download 78. Clicking on 78.0 just led to more links that got me nowhere. Is it possible to download version 78 from this or any site? Thank you. heaton5

Your Safari said you were running Mac OS X 10_15_7. That is not correct?

The last version for Mac OS X 10.9, 10.10 and 10.11 is here:

https://ftp.mozilla.org/pub/firefox/releases/78.15.0esr/mac/en-US/

If you prefer a different locale/language than U.S. English, click the .. link above the two file names on that page to open the folder listing all the available locales. You probably want the one that appears in the address bar while you are using this site.

After you download the DMG file, you can refer to the other steps in: How to download and install Firefox on Mac.

Please note that support ended for the extended support release of Firefox 78 in October 2021, and it is not receiving any more security patches.

Also to note, Firefox 79.0 and later including the current Fx 96.0 and 91.0 ESR requires macOS 10.12 (ten.twelve) at minimum to run.

Re "Your Safari said you were running Mac OS X 10_15_7." My inquiry is about a different computer, running 10.11.6. Your solution worked for me, jscherr2000. Don't know why I was unable to find that. Many thanks.
