We would like to show First-Run Triplets on the new tab for a longer period of time beyond just the initial launch of the browser. The scope of this work is to extend the time they are shown, without any other major changes in design or functionality.

Some new telemetry will need to be collected in order for us to track how users engage with these extended triplets, as well as some frequency cap information and blocking functionality.

[Tracking Requested - why for this release]: We'll use this bug to uplift the "extended triplets" feature for relationships kpi

Bug 1569303 - Extended First Run Triplets

Includes 9 bugs: https://bugzilla.mozilla.org/buglist.cgi?bug_id=1560065%2C1568909%2C1570026%2C1571817%2C1572378%2C1570754%2C1570481%2C1571442%2C1573209

Beta/Release Uplift Approval Request

• User impact if declined: Could easily skip over the one-time triplets cards from about:welcome instead of seeing them a bit more on new tabs
• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: Yes
• Needs manual test from QE?: Yes
• If yes, steps to reproduce: See QA scope: https://docs.google.com/document/d/16ZKPpOaPs3FLmTNePPNeNBjutCPRZrGeScDQMtWPYSA/edit#heading=h.fwc5z5t7r484

Set app.normandy.user_id to a string pref value 99 to test "holdback" experiment (i.e., no triplets on new tabs).

• List of other uplifts needed: bug 1567601 and bug 1569300
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): The patch for uplift is on top of both bug 1567601 and bug 1569300 that touch some shared code. The behavior changes are relatively straightforward of additionally showing the about:welcome cards on new tabs although the patch is somewhat large as it includes refactoring to show the triplets on more than just about:welcome. Given the startup nature of showing about:welcome or about:home early, experimentation is built in like how it was done for Trailhead 67 dot release.
