That doesn't seem to say anything about what gets transmitted to or from Google? Certainly it's not your visited URLs.
> And for the record, FF android prioritizes Google searches over history leading to accidentally visiting the Google search for a web page I often frequent.
For search suggestions we send what you've typed, not full URLs. I'm not sure what happens when pasting a URL but I would recommend using Paste & Go in that case. Search suggestions can be disabled too in the app settings.
