Graze is a browser extension for Chrome by Jared Zimmerman, which currently works for Mastodon (but there’s a feature request in to add support for other services too).
You can install it from the Chrome App Store.
You know how it’s really annoying when someone, say, links to a Mastodon profile or a post on an instance other than your own? You have to enter your details, because of course that other instance doesn’t know who you are or where to send the boost or follow request.
Graze fixes that. Next time you press follow, it doesn’t matter which instance you’re on - Graze will ensure to trigger a follow from your home instance. And its not limited to follow: No need to copy and paste links into your search bar, to follow, boost, bookmark, reply.
Graze additionally has options to expand snippets for linked URLs to show a much richer view, as well as a few other convenience functions to make browsing remote Mastodon instances more useful.
If you use Mastdon from Chrome, you really should install Graze.
