A) Maybe not you, maybe not me or anyone else here, but 99.99% of the rest of the world? And when the rest leave, is Mozilla really going to be able to justify maintaining a browser for those that remain? B) There might not be a website that would do it, but what about if practically all websites with any corporate backing did it?
My understanding was that the browser vendor itself would be the attester. So if Google says it’s Google Chrome, it probably is. Unless you somehow reverse engineer how Google decides that it’s Google Chrome and spoof that or something…
