Mastodon Chirper

Mastodon Chirper is a browser extension which integrates the Mastodon social network with the twitter.com UI.

The extension offers a friendly way of transitioning to Mastodon, or at least getting exposure to the many different growing Mastodon communities, without needing to leave Twitter.

Your Mastodon timeline is automatically downloaded periodically and gets interspersed between your timeline's tweets.
