I agree that the standard channel is for most people. I would put myself in that category, but a friend recommended I try Nightly and it's certainly worked for me. No crashes, no other problems and it is significantly faster than the earlier versions I was using.

Re updates - my Edit/Preferences/Advanced/Update shows:
Automatically install (recommended)
Check for updates but let me choose (I use this)
Never check (not recommended - security risk)
