It appears to add fewer than other browsers, but I'm not quite sure why it adds "?channel=fenc&client=firefox-b-1-d" to searches when only the q/query parameter is needed for them to work.
Update: I have figured out how to remove the client parameter, though I'm still not sure why the channel parameter is there. Any idea what that's about?
Why does Firefox add tracking parameters to Google searches? ( fedia.io )
