Tried to update Firefox as advised by browser, but download doesn't support OS 10.11.6. Don't want to update OS as system is old. What is the last version of Firefox that I should download?

The last version for your macOS 10.11 is Firefox 78.14.0 esr. There will only be one update to 78.15.0 ESR next week and then support for your OS will end. Your Firefox version will continue to work, but you may encounter issues with websites that only support current releases.
