My experience migrating to MV3 I migrated my addons to MV3, and learned that version numbers increase, DRY is overrated, and 3 and 15 are probably important but I have no idea why. What I didn't learn is how MV3 made my addon better.
What is Manifest V3 and why is Google pestering me about it? If you've ever dug into the underpinnings of a browser extension, or maybe even created one yourself, you've seen the manifest.json file that acts as a sort of usage guide for an extension. Not the kind of usage guide most people would want to read,
