I have been using Firefox for many years on my Mac 10.11.6. Firefox recently offered me an update, I duly downloaded and attempted to update but apparently my Mac is too old, and now cannot get back to the former version of Firefox:0( Problem is I have lost all my passwords to sites that I visited and I cannot find the correct old version of Firefox to re-install, can you please point me to a link that allows me to install the OLD version. I have tried many times throught the ESR channel but it wont work as it is trying to install a higher than possible version:0( Hope for a resolution Cheers Roy from England.

Firefox since Fx 79.0 and later including the current Fx 96 and 91 ESR requires macOS 10.12 (ten.twelve) at minimum.
Besides updating your OS to macOS 10.12 or later, the most current Firefox version you can install on macOS 10.9, 10.10 and 10.11 is Fx 78.15.0 ESR though it is EOL with no more updates.
