1844701 - Add support to display Feature Callouts via about:messagepreview

Status: VERIFIED FIXED

(Firefox :: Messaging System, task, P3)

Description

[Shane Hughes [:aminomancer]]

Using the new hookup between FeatureCalloutBroker and ASRouter implemented in bug 1821826, it should now be possible to extend about:messagepreview to handle feature callout messages. You can already show feature callouts from the ASRouter devtools. So it should be pretty simple to show them in about:messagepreview as well. See bug 1821820 for an example of how to add a surface to about:messagepreview.

I have verified this task by navigating to the Test URL after setting the “browser.newtabpage.activity-stream.asrouter.devtoolsEnabled” pref to “true” in the “about:config” page, and I can confirm that the Feature Callout is correctly displayed.

Verified using the latest Firefox Beta 118.0b2 (Build ID: 20230829180158) installed on Windows 10 x64, macOS 13.5.1, and Ubuntu 22.04.
