1) What questions will you answer with this data?

It answers how our users navigate within tabs.

2) Why does Mozilla need to answer these questions? Are there benefits for users? Do we need this information to address product or business requirements?

This provides information about user behavior on navigation within tabs.

3) What alternative methods did you consider to answer these questions? Why were they not sufficient?

Current methods have not previously recorded this type of telemetry.

4) Can current instrumentation answer these questions?

No.

5) List all proposed measurements and indicate the category of data collection for each measurement, using the Firefox data collection categories found on the Mozilla wiki.

Note that the data steward reviewing your request will characterize your data collection based on the highest (and most sensitive) category.

Did a user tap the refresh button in the toolbar?	Category 2	#9278
Did a user navigate to a previous link in tab history but swiping from the left edge of the screen?	Category 2	#9278

6) How long will this data be collected? Choose one of the following:

Until 2022-07-01.

7) What populations will you measure?

All release channels and locales.

8) If this data collection is default on, what is the opt-out mechanism for users?

Users can opt out of of data collection by disabling Usage and technical data from Settings → Send Usage Data.

10) Where do you intend to share the results of your analysis?
