Can anyone confirm if the latest version of Firefox 91.0.2 will install and run (using standalone installer)on OSX Sierra 10.12.6 ? I assume not but just checking. Helping a friend. My research suggests not. Best, last compatible version i can see would be possibly version 48.0 or if not version 45.9.0esr ? Would appreciate quick response if possible as have to talk friend through update as soon as i can. Much appreciated.
