Fatebook for Firefox av Adam Binks, jspicer

Rapidly record a prediction on any webpage by pressing Ctrl-Shift-F.

Then you can paste an embed of your prediction, right into the webpage (e.g. a Google Doc, Notion document, Asana item, or tweet).

This extension also transforms links to Fatebook predictions into interactive embeds - anywhere on the web. Everyone reading can add their own predictions, add comments, and get notified when the question resolves as YES, NO or AMBIGUOUS.
