Not at all related to this but posting for visibility. Firefox never updates automatically for me and I've uninstalled, removed my account and other basic troubleshooting steps I've found through Googling never help. I have to run the installer with every update. And that would be fine but it resets some settings that don't sync with your profile, as an example, it always changes language spell check back to US English from British or Australian English. Its giving me the shits. How do I fix the above?
