about:welcome Audit integration of email first without iFrame

[davismtl]

On about:welcome , they've rebuilt the /firstrun experience without the iframe.

From an FxA standpoint,

• let's sign off to make sure it is well integrated with proper parameters.
• let's confirm we have a way to track the email first form view without the iFrame

The only UX prob I detected is that it doesn't support a signed in state however I question how regularly a signed in user will get to about:welcome

@ericawright here's an example of how the integration works jpetto/bedrock@af5d94a

Let us know if there are any issues, especially with origin requests

@vladikoff thanks, I was looking into it this morning briefly and there was an issue with the origin request. I saw @piatra assign themselves to the issue though, I'll double check to see if they will be implementing it.

This is done!

@shane-tomlinson & @philbooth according to the bug, QA sees flow_begin_id and flow_begin_time in Firefox 63.0a1 (nightly).

However, when I look in Amplitude, I don't see any email_first form views:

What am I doing wrong? Am I looking at the right params here? Is it just that there is no volume in nightly so this is normal? I tried to trigger the event myself but no luck.
