2020798 - Build the UI code for asrouter-newtab-message

Status: VERIFIED FIXED

(Firefox :: New Tab Page, task, P1)

Description

[Shane Hughes [:aminomancer]]

This bug is for building the UI component (reading JSON messages and rendering them) for the asrouter-newtab-message from bug 2020100. That bug adds the necessary infrastructure, leaving for OMC the final steps of parsing the JSON, rendering it, and styling it.

I have verified this task using the steps from here, and I can confirm the following:

• The "TEST_ASROUTER_NEWTAB_MESSAGE" message can be successfully triggered from the "about:asrouter" page.
• Confirmed that the messages can be successfully delivered through an experiment and are successfully triggered (got enrolled in the "Kitified value prop experiments on New Tab - Re-run" experiment)
• The message elements respect all the default browser theme colors.
• Verified that the asrouter message impressions are being recorded in about:asrouter#devtools-impressions.
• Verified that the frequency caps, groups, and targeting criteria are respected.
• Verified that all the message elements can be accessed through keyboard navigation.
• Verified that the message is blocked in the ASRouter page after dismissal and no longer triggered on future new tab pages.
• Verified that the IMPRESSION, CLICK (both primary and secondary buttons), and DISMISS GLEAN telemetry pings are successfully generated and sent.

Verified using the latest Firefox Release 150.0.1 (Build ID: 20260427013024) on Windows 10 x64, macOS 26.3.1, and Ubuntu 24.04.
