Firefox since Fx 79.0 and later including the current Fx 98 and Fx 91 ESR requires Mac OS X 10.12 (ten.twelve) at minimum.

Besides updating your OS to Mac OS X 10.12 (ten.twelve) or later, the most current Firefox version you can install on mac OS 10.11.6 is Fx 78.15.0 ESR though it is EOL with no more updates.

I'm a little old lady, so i don't seem to understand what is in the links in your reply, @James. i have a very old computer and 10.11.6 is the "latest" version it can use.

Would you please, and simply, direct me to the version of FF that i can use?

sooo much appreciated!! Gramma Lo
