Starting in Firefox version 142, Mozilla released a “Link Previews” feature.

While the feature is problematic, commenters pointed out that some previews are helpful – e.g. on Wikipedia, where a preview will appear when people hover over a wiki-linked page.

Other commenters pondered about some minimal way to replicate this elsewhere, and it seemed to be worth investigation. Read on as I propose an enhancement to the Fediverse (and maybe even web standards) to make Link Previews great: the Link Preview Manifest.

@yoasif interesting proposal, I have been thinking about Link Previews for clients, a typical concern there is CORS. But I didn’t see anything addressing that in the proposal.
