1675503 - Measure page performance over HTTP3

Status: RESOLVED FIXED

(Core :: Networking: HTTP, task, P2)

Description

[Dragana Damjanovic [:dragana]]

The following 3 existing probes are relevant:

• TIME_TO_FIRST_CONTENTFUL_PAINT_MS
• TIME_TO_NON_BLANK_PAINT_MS
• FX_PAGE_LOAD_MS_2.

Probes needed:

• TIME_TO_FIRST_CONTENTFUL_PAINT_MS_HTTP3 - The same as TIME_TO_FIRST_CONTENTFUL_PAINT_MS but only records pages that have used HTTP3 to fetch the main document
• TIME_TO_FIRST_CONTENTFUL_PAINT_MS_HTTP2_SUP_HTTP3 - The same as TIME_TO_FIRST_CONTENTFUL_PAINT_MS but only records pages that have not used HTTP3 to fetch the main document but the server the main document has been fetched from supports HTTP3
• TIME_TO_NON_BLANK_PAINT_MS_HTTP3/HTTP2_SUP_HTTP3 - This is similar as above to separate probe TIME_TO_NON_BLANK_PAINT_MS into: 1) pages that have used HTTP3 and 2) pages that have not used HTTP3 but support HTTP3
• FX_PAGE_LOAD_MS_2_HTTP3/HTTP2_SUP_HTTP3 - This is similar as above to separate probe FX_PAGE_LOAD_MS_2 into: 1) pages that have used HTTP3 and 2) pages that have not used HTTP3 but support HTTP3

This will be collected for sites that have used HTTP3 and for sites that support HTTP3 but HTTP3 has not been used.

If the request is for permanent data collection, is there someone who will monitor the data over time?

Yes, :dragana is responsible.

Using the category system of data types on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1, Technical.

Is the data collection request for default-on or default-off?

Default on for all channels.

Does the instrumentation include the addition of any new identifiers?

No.

Is the data collection covered by the existing Firefox privacy notice?

Yes.

Does there need to be a check-in in the future to determine whether to renew the data?

No. This collection is permanent.
