I have Firefox 52.2.1 (32-bit). Windows XP Service Pac 3. 2 gig ram. Update channel is esr. From mozilla ---- Firefox (esr update) is intended for groups who deploy and maintain the desktop environment in large organizations..... I am not a large organization. Just a home desktop environment. 1- How did I get on esr update channel? 2- Should I be on it? 3- How do I get back to whatever channel preceded esr? 4- Should I go back? I've tried re-installing, but it automatically picks esr to install. Thank you.
