Going through Cancer therapy for the next few months. iMac from 2008 can't upgrade system beyond Os 10.11.6; I can't seem to download any compatible version of Firefox. I'm using Brave, but it blocks about half of all sites; sez they're un-secure or un-verifiable.

I expect to be able to go back to work eventually, but this is ridiculous. Security systems are progressively narrowing my options and cutting me off from the whole world.

Firefox 79.0 and later has required macOS 10.12 (ten.twelve) at minimum to run so you will need to upgrade to macOS 10.12 (ten.twelve) or higher to use any more current versions of Firefox. Though you believe your hardware does not support that option.

Fx 78.15.0esr is the most current version you can use though it is EOL with no more updates. 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/
