1756900 - Trim down default PDF viewer telemetry.

Status: RESOLVED FIXED

(Toolkit :: Default Browser Agent, enhancement, P3)

Description

[Nick Rishel [:nrishel]]

Follow up to https://bugzilla.mozilla.org/show_bug.cgi?id=1742674.

After we have an understanding of what PDF viewers are commonly set to default, we need to trim down to a set of observed viewers. This will largely follow what already exists for default browsers.

Romain: would you like to take a crack at preparing the top N list from the WDBA default PDF handler data (per looker)? It's clear some of these need to be grouped. Perhaps we keep groups that amount to >1% of the pings and see how many that is?

While we're here, it would be helpful to trim whitespace from the raw PDF handler string.

Comment 3

[Nick Alexander :nalexander [he/him]]

Also while we're here, perhaps we could track down why we're getting null at least 10% of the time (for Firefox 105, so we should be fishing the PDF default).

I believe we chased this down to an error when inspecting the data - search included FF versions prior to the telemetry being added.

Worth noting that I did a lot of the relevant labour in this query; we could implement that normalize_pdf_default and be done here.

Comment 6

[Nick Rishel [:nrishel]]

The "Other" category in that query is still fairly large, probably worth a round of finding trends in it.

The bug assignee is inactive on Bugzilla, so the assignee is being reset.

Request for Data Collection Renewal

1. Provide a link to the initial Data Collection Review Request for this collection.
   https://bugzilla.mozilla.org/show_bug.cgi?id=1742674

2. When will this collection now expire?
   Never

3. Why was the initial period of collection insufficient?
   Initial collection was intended as a precursor to determine what we wanted to track. Now that we have that data we are trimming it down to better match our lean data policy.

Hey, sorry, was at a work week and then sick most of this week. Not a big deal in this particular case, but note that, in general, the data-review should be approved before landing. You can ping the data-stewards channel on matrix if you don't get a response within 24 hours and someone else should be able to help with the review. Looking at this now.
