You still need to manually approve on the mobile app each time you need 2FA.

I wanted 2FA authentication from my desktop, so I don't always need to grab my phone, log in, go to home screen, open the app, approve, BLAH BLAH. Still the same huge hassle with this extension.

For those people saying "bUT yoU wIlL gET HAcKeD!!!11!!", no, if this was an actual 2FA-extension then you would be able to set up your PC/Browser to be the second authentication.
