Fediverse Actions Anyware by kotet

Found a post on another Mastodon instance and want to favourite it? Normally you would have to copy its URL, open your own instance, search for it there, and act on it from there. Fediverse Actions Anyware does this for you from the page you are already on.

How it works
- Register your Mastodon account (your "home account") from the toolbar popup. You sign in on your own instance's page; the extension never sees your password.
- Open a post on any other Mastodon instance where you are not signed in. Its reply, boost, favourite and bookmark buttons are replaced with copies marked by a thin underline.
- While a tab's buttons are replaced, the star in the extension's toolbar icon turns gold.
- Press one, and the action runs on your home instance. The underline shows the state: moving dashes while it runs, a thicker purple line once the post is favourited, boosted or bookmarked, and dots if it failed (hover over the button to see why). Press it again to undo.
- Reply opens the same post on your home instance in a new tab, where you write the reply.

Works on
- Post pages and timelines of the standard Mastodon web interface.
- Several home accounts can be registered; the one selected in the popup is used.
- On pages of an instance you are signed in to, the extension adds nothing, because the page's own buttons already act as your account there.

Not supported yet
- Other fediverse software such as Misskey, and alternative Mastodon web interfaces.
- Firefox for Android.
- Settings (for example, choosing which buttons to replace).

Data
The extension talks only to the Mastodon instance you register. When you press one of its buttons, it sends the URL of that post to your home instance to look the post up there, then performs the action. Nothing is sent to the developer or to anyone else. See the privacy policy for details.
