[User Story] As a product team, we want to know how many users use "Preferences" and their behaviors so that we can make informed decisions about this feature [Acceptance Criteria] 1. Out of all the users that are active in a month, we know the % of them who access "Preferences" 2. Out of all the users who access "Preferences" in a month, we know how many times they acess to "Preferences" 3. We know how many total access to "Preferences" in a month 4. We know the % of users go to "Preferences" by clicking on hamburger menu/ about:home/ menu bar (actively) instead of clicking on buttons in prompts (passively)? 5. For all the users who access to "Preferences" in a month, we know how many go to "General", "Search", "Content", "Applications", "Privacy", "Security", "Sync", and "Advanced"

The data can be found through the telemetry ID: FX_PREFERENCES_CATEGORY_OPENED.

Filed below bugs because we have the five pages in our new design spec[1]. Bug 1350267 - Telemetry for General page Bug 1350268 - Telemetry for Downloads & Links page Bug 1350269 - Telemetry for Firefox Account page Bug 1350270 - Telemetry for Privacy & Security page Bug 1350272 - Telemetry for Updates page [1]: https://mozilla.invisionapp.com/share/P4ACQT1E3#/screens/217167547

We might also need to discuss the priority of each page or each section on the pages.

The rest of telemetry probes will be added after the Reorg job.
