When I was a kid I walked to the bus stop, played outside with a lot of freedom, etc. The rule for most kids was to go home when the street lights came on, and there was usually a border you weren’t allowed to cross - for me it was a road with a lot of speeders and crazy drivers.
Google was recently successfully sued for being anit-competitive by paying third parties to set Google as the default search engine.
That payoff by Google is like 90% of Mozilla’s income, which is probably disappearing. So yeah, they’re in full panic to fill that gap.
