Downloaded the latest version, didn't save both copies, lost last version, now won't run, iOS incompatible, can't get new version iOS.
I need a link to download the last version of Firefox that worked with my iOs 10.11111111... version for my OLD MacBook Pro. (2009)... Can't afford new Mac and newest version of iOs won't run on this MacBook... Too old... Same story: need new, no $$$... So, I what I need is a link to the old version of Firefox that I CAN run on my MacBook... One that works with iOs 10.11116 or whatever...
Thanks, humans smarter than me...,
Kate

Firefox since Fx 79.0 and later including the current Fx 100 and Fx 91 ESR requires macOS 10.12 (ten.twelve) at minimum.
Besides updating your OS to macOS 10.12 (ten.twelve) or later, the most current Firefox version you can install on macOS 10.11 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/
I moved this thread from Firefox for iOS (for iPhone/iPad) section to Firefox section since you are using macOS.
