I mean read these commits, Most of the development effort for Firefox is obviously not AI related theirs so much plumbing, web standard chasing, maintenance that needs to be done instead https://github.com/mozilla-firefox/firefox/commits. A literal "Ask claude to summarize my webpage" is like an intern group project
Mozilla seems to want to put funding into infrastructure for helping build open source AI models, IMO I don't really think this is their expertise so it seems like not a very good idea. Could also be a useful revenue source.
The more interesting thing is if AI adopts an ads model, firefox can sell the default AI integration in the same way they sell the default search engine to Google. Would help their revenue problem.
