The “Manifest V3” rollout is back after letting tensions cool for a year.
Firefox is my daily, but the fact I have to fire up a chromium browser to use web serial or midi is an endless annoyance. Mozilla won’t add that functionality as they see it as a security risk.
Honestly, in my opinion it kind of is (though I’m not an expert on it). Except for convenience I don’t think a browser should be allowed to access my USB devices. Though I would welcome it if it was enabled with the same kind of request that pops up when a browser wants to access the microphone or camera.
