None!
Use Alby or Nos2x by fiatjaf for Chrome/Firefox.
I think it utilizes NIP-07 to sign for events 😊

Got it. It would be helpful if sites like iris gave that hint. The first thing I see there is "Private key access" -> "paste a private key"
Hmm yeah you might have a point, I think the main worry is that people would be turned off from browsing any further if they had to go to the length of installing an extension etc. Same time though the extension pretty much makes ALL of nostr on the web well... do-able to me.
Every Nostr website that requires you to login should have a NIP-07/Extension button clearly on the side to make the onboarding process more seamless to the more popular clients perhaps.
