The link in the UI doesn't mention sponsorships anywhere. But this page does:
Who are Mozilla’s partners for sponsored suggestions?
We partner with organizations to serve up some of these suggestion types... For sponsored results, we primarily work with adMarketplace, while also providing non-sponsored results from Wikipedia.
This page links to the adMarketplace Privacy Policy which makes it pretty clear this company is okay with collecting your IP address and passing it to further unnamed entities.
Elsewhere, they say Firefox sends them "the number of times Firefox suggests or displays specific content and your clicks on that content, as well as basic data about your interactions with Firefox Suggest", and then will share interaction information "in an aggregate manner with our partners".
Update: Switched the link from the Desktop to the Mobile version. Added more quotes from FF, and bolded info about their one named AdTech partner.
Yeah, you need to clean up the browser before using it because the browser is full of advertising and tracking by default. The massive telemetry and reflinks and "hidden" extensions need to be removed, as always.
It looks like this has been in the desktop browser since 92 (released in 2021) but a new addition to Firefox 120 and beyond. But it's a staged release so not everybody is going to see this "experiment" at once.
You can't Betterfox your mobile Firefox, can you? Thank goodness for decent mobile browser forks...
That's interesting. I've been a Firefox Beta holdout, thinking about adopting Fennec as my daily driver, but I understand the value of sticking to the browser that receives the most timely security updates.
The biggest downside is, it looks like the modifications aren't intended for the mobile app, but they apparently partially work. But in a good way:
using the base user.js on Firefox Android only improves speed and battery life, which is great because telemetry can be very battery hungry.

After a decade of not using Firefox I just started using it again a few weeks ago. While desktop is absolutely fine, using the Android version is just a bad experience. Coming from Vivaldi Mobile it feels like a massive downgrade from a polished modern mobile browser down to an early alpha hobbyist project.
If it weren't for seamless tabs and bookmarks synchronization (everything else seems not to be synchronized at all) I would keep Vivaldi on Android because its just so much better.
