Mozilla has plenty of telemetry that is opt out, not to mention opt-out "experiments" that have collected browsing data and gave it to third parties.
That is not my definition of explicitly signing up for their services.

Mozilla doesn't have your data.
The only way Mozilla would ever have any of your data is if you explicitly signed up for one of their services to hold your data for syncing purposes or something.
Unless you very actively said "Take my data please!" at some point, there really are very few things Mozilla would be able to do to get at your data. (In fact, by far the easiest thing for them to do would be to forget about using firefox and just buy the data from Facebook or Google.)
