I created a browser extension to help transition to Mastodon[0]. If you are curious about Mastodon but don't yet feel like you can leave twitter.com then it's a great way to get started. Essentially it injects Mastodon posts into your Twitter timeline, so you can retain your existing Twitter following while getting exposed to Mastodon.

I'm working on a Firefox version right now as well.
