Latest nightly builds of Firefox 139 include an experimental web link preview feature which shows (among other things) an AI-generated summary of what that page is purportedly about before you visit it, saving you time, a click, or the need to ‘hear’ a real human voice.

I wonder if the preview does a pre-fetch which can be identified as such? As in, I wonder if I'd be able to serve garbage for the AI summarizer, but the regular content to normal views. Guess I'll have to check!

Update: It looks like it sends an X-Firefox-Ai: 1 header. Cool. I can catch that, and deal with it.

I agree with your sentiment. It's sad that your (or my) website can't respond with a X-This-Website-is-not-AI-Garbage header to indicate that "Hey user, you can actually just open this website and read it and get the infos you need without an AI assistant.".

I'm pretty sure Firefox's preflight request will also not load ads and so could be seen as a bad scraper.
