Various older macOS versions are no longer supported. This started with OS X 10.9/10.10/10.11 what includes the 10.10 version you use and those were moved to 78.15.0 ESR as the last available version and you can't update to newer Firefox versions.

Firefox 78.15.0 on the Mozilla CDN server:

Recently support for OS X 10.12/10.13/10.14 was dropped and those were moved to 115.8.0 ESR and still receives updates until September this year. The current minimum is macOS 10.15 or newer.
