Hello folks,

I'm looking to upgrade my FF browser as much as possible, but I need to run Mac OS X 10.9.5 (for legacy software) on my older iMac.

Currently running "78.15.0esr (64-bit)" and the "About" window says "Firefox is up to date" and "You are currently running on the esr update channel" (Not sure what that means)

Any help would be greatly appreciated! Thank you.

TJ

Firefox since Fx 79.0 and later including the current Fx 95 and 91 ESR requires Mac OS X '10.12' (ten.twelve) at minimum. ESR stands for Extended Support Release and was meant more for Enterprise users in mind as they like stability.

Besides updating your OS to Mac OS X 10.12 or later, the most current Firefox version you can install on mac OS 10.9.5 is Fx '78.15.0' ESR though it is EOL with no more updates.

In case you ever need the Firefox 78.15.0esr file. https://archive.mozilla.org/pub/firefox/releases/78.15.0esr/mac/en-US/ other locales at https://archive.mozilla.org/pub/firefox/releases/78.15.0esr/mac/
