How can I get the download for version 78 for Firefox? My Mac is on 10.11.6 and my Firefox won’t open bc the newer version isn’t supported. I need the old version and can’t seem to find a way to download it. Please help!

If you can update your macOS to at least 10.12 (ten.twelve) then you would be able to run Firefox 115 ESR which is currently at Fx 115.17.0esr and is being updated till at least Fx 115.21.0esr in March 2025 unless Mozilla extends updates again.
