This difference of views, decades ago now, culminated with a screaming fistfight in San Jose parking lot.
The "winning" camp of this altercation stayed at Mozilla, and Firefox couldn't auto-update for another... twelve years? Fourteen?
The "loser" left Mozilla and went to Google to become one of the earliest members of the Chrome team.
You don't know what version of Chrome you're using right now. You don't care. It's just 'Chrome'.
