We’ve made the hard decision to end our experiment with Mozilla.social and will shut down the Mastodon instance on December 17, 2024. Thank you for being part of the Mozilla.social community and providing feedback during our closed beta. You can continue to use Mozilla.social until December 17. Before that date, you can download your data here (https://mozilla.social/settings/export), and migrate your account to another instance following these instructions (https://support.mozilla.org/en-US/kb/mozilla-social-faq).
I swear Lemmy comments for YouTube had a feature that let you open it for any page, but it seems the GitHub and Firefox page been deleted.
Edit: Looks like I’ve still got a fork: https://github.com/Steve-Tech/Reddit-Comments-for-YouTube (it says Reddit, but works for Lemmy too)
