installed the wrong update
i accidentally installed the latest update not realizing it will not be compatible with my iOS 10.11.6 operating software. Can I reverse this and go bak to using the browser version I was using prior to this update?
Chosen solution
Firefox since Fx 79.0 and later including the current Fx 100 and Fx 91 ESR requires Mac OS X 10.12 (ten.twelve) at minimum.
Besides updating your OS to Mac OS X 10.12 (ten.twelve) or later, the most current Firefox version you can install on mac OS 10.11.6 is Fx 78.15.0 ESR though it is EOL with no more updates.

Sounds like you are actually referring to macOS and not the mobile iOS. Moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section.
