1377567 - Refine telemetry for toplevel data: URI loads

Status: RESOLVED WONTFIX

(Core :: DOM: Security, enhancement, P2)

Description

[Christoph Kerschbaumer [:ckerschb]]

We should refine our telemetry in the following way:
* add referrer URI
* add contentpolicytype
* check if data URI loads a form

Another thing we discussed was differentiating between:

- typed-in URLs
- URLs loaded from the outside (e.g. link clicked in Thunderbird)

I discussed things with smaug and it seems we don't have the information to determine whether a click comes from outside. Dan, you mentioned we potentially have a flag within docshell to query that information, can you recall what flag that was?

LOAD_FLAGS_FROM_EXTERNAL might do what you want; dunno how reliable it is (added by the front-end).

Don't we already have telemetry for those?

Since we got green lights to ship Bug 1331351, we are not going to need refinement on the telemetry here.
