Can't really figure it out. I try to login and put mastodon.social in the Add instance field, but I get an error:
> Error: undefined. Is this a valid Mastodon instance? Is a browser extension blocking the request?

Interestingly, the reason is (as I discovered) that most of these tools consider cross-origin requests as a signal of a third-party tracker or ad, and therefore block it. Pinafore works by talking directly to the instance's API, and so the instance itself is suspected to be a third-party tracker. ️
