It's nothing like pocket ads. They send everything you type and the item you click on. Take a look at the "What data is shared if you enable contextual suggestions?" section.
>To help you find information faster, Firefox Suggest uses a service provided by us to offer relevant suggestions to the text you are typing. When contextual suggestions are enabled, Mozilla receives your search queries. When you see or click on a Firefox Suggest result, Mozilla collects and sends your search queries and the result you click on to our partners through a Mozilla-owned proxy service. The data we share with partners does not include personally identifying information and is only shared when you see or click on a suggestion.
I don't think it reads the way your comment implies.
You may be right, but it's very unclear. I came to my conclusion because Firefox calls every result a "Firefox Suggest" result (see the title at the top of the results).
From https://blog.mozilla.org/data/2021/09/15/data-and-firefox-su..., it looks like Firefox (currently) matches your search terms against a local list before forwarding them. So not everything is sent, but anything including a term specified by the advertising agency.
It's unclear if it includes the entire search query or just the single word. That same blog post seems to indicate that mozilla "may" send the entire query. It also appears that Mozilla is sending city level location data.
Of course, that same blog post implies that the feature is opt-in (which it definitely isn't).
