Can confirm, it works, stays out of the way, and gives you a list of accounts it has seen when you click on it.

I've really enjoyed having this extension installed for a couple weeks now.

It's unobtrusive, so it doesn't interrupt what I'm doing. But occasionally I'll glance up and see that it has collected a few new Mastodon users.
Having a link to both the website I visited and the verified Mastodon account helps me remember where I was when I encountered the new account.

Thank you for making this!
