Firefox update for Mac OS Sierra?

I'm on a Mac Pro running OS Sierra, 10.12.5. I cannot upgrade this Mac due to a specific version of Pro Tools that I have, that will only run on this Mac OS. My current version of Firefox is 115.0.3 (64-bit) on the ESR channel.

My question is this: Is there another version I can update Firefox to, and how? Or is there another browser you would recommend I use?

Thanks, Ray Kallas

Firefox 115 ESR currently at 115.18.0esr and will be updated till at least 115.21.0esr in March 2025 is the most current Firefox version you can run on macOS 10.12, 10.13, 10.14. https://support.mozilla.org/en-US/kb/firefox-users-macos-1012-1013-1014-moving-to-extended-support

Firefox 116.0 and later requires macOS 10.15 or later to run.

The Firefox 115.18.0esr.dmg can be downloaded from https://archive.mozilla.org/pub/firefox/releases/115.18.0esr/mac/ and each folder in the language like en- is English.

Pretty much every other web browser has already dropped macOS 10.12
