All the Safari search engine extensions work the same: https://lapcatsoftware.com/articles/2025/2/2.html

Interesting, something must have changed then - the qwant search extension definitely does not leak the search to the default search engine - I checked myself with Proxyman.

I just tested with Little Snitch and saw leakage to Google.

It's a race condition, so you might not always see it.

I don't know your setup but in my opinion something like proxyman / mitmproxy or even Wireshark would be the better way to analyse this. I tested quite often and never saw the leak with Qwant.

I have Proxyman and Wireshark. IIRC I used Proxyman also when writing my blog post.

In any case, Little Snitch is not lying and inventing packets. I don't know why you aren't seeing anything, but as I said, it's a race condition, so that can happen, and in any case, I would say that it's a better way to analyze this by adding Little Snitch to your setup.

I quickly downloaded the kagi extension for testing and there I can see the leaking - the Qwant extension still does not leak. Maybe you could also test the Qwant extension?

There's really no magic or mystery here. The extension is simply using this API: <https://developer.apple.com/documentation/safariservices/sfs...>
