Where are you getting this from?
TL;DR you are not sending us your browsing history.
If telemetry and studies were turned off, your browser wasn't sending us this unique id.
If you had kept them enabled, for normandy telemetry you would have been sending us the data described at https://firefox-source-docs.mozilla.org/toolkit/components/n...
