Adds support for embedding Facebook and Instagram posts in Block Editor (Gutenberg) and Classic Editor. This feature was removed in WordPress core due to deprecation of legacy APIs WordPress core used.
Prior to WordPress 5.5.1, WordPress had support to embed Instagram and Facebook photos, videos, notes, quizes, etc in posts created with Block Editor and Classic Editor. However, Facebook removed this legacy API in October 2020, and this plugin implements the new APIs to bring back support for Facebook and Instagram content embedding.
Note that you will need to register a Facebook developer account and create an app to get API credentials that this plugin uses. There is no coding necessary, but an API key needs to be created and set for the plugin.

As the title suggests, this is written beautifully and works perfectly.

No bloat.

On-screen links to where you need to go at facebook and documentation.

And the ability to define keys in wp-config make it great for multisite.

Works perfectly, and elegantly coded for MultiSite

Works exactly as advertised. Thank you.

That does it without any extra clutter added to the admin. Thanks :)

Perfect

An easy way to drop some weight if you don’t need the functionality that the plugin disables. For me this has been a “set and forget” plugin. 

Does what it says, has been reliable

thanks

Finally, a no-fuss plugin that does exactly what it promises! Disable Embeds by Pascal Birchler is perfect if you're tired of WordPress's automatic embed features slowing down your site. Just activate and boom - no more unwanted embeds cluttering your content or others embedding your posts without permission. Love how it removes all the JavaScript bloat too. The best part?
