Mastodon often fails to show up-to-date context and information on posts from remote instances. This addon does that properly.

  • See all the replies to any post on your home instance. Local and remote replies are now loaded in parallel, so there is no extra delay.
  • Interact with all the remote posts as normal. They will be fetched to your instance as needed.
  • See up-to-date boost/favorite counts on posts.
  • See the actual last 20 posts in any user's profile (page refresh may be needed).
It should work reliably on mainline Mastodon versions 4.0 and up, your mileage may vary for older instances or forks.

Missing features

  • The extension currently does not account for personal block lists.
  • Only Mastodon is supported as the home instance.
Make sure to open the addon settings and type in the instances it should be active on!

It doesn't seem to do anything! Please check that you have entered the instance domain name in the extension settings, and that it doesn't complain about permissions. If upgrading, you might need to delete the extension completely, restart the browser and install again. If nothing helps, please report a bug. Thanks!

Does this support servers other than Mastodon? It can fetch statuses and contexts from Akkoma/Pleroma and Misskey/FireFish/Sharkey/IceShrimp/etc.
