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?

I did: https://news.ycombinator.com/item?id=43175181

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

I don't know why it's different for you and me then. I tested Qwant once again and saw not one call to duckduckgo (my default search engine) - now I'm over 100 searches while analysing with proxyman without one leak. The kagi extension on the other hand leaked all my first 3 searches. Something must be different.
