Firefox Tracking Flags

(firefox63 fixed)

Chrome/WebKit do not appear to implement marquee events (start, bounce, finish) at all:

So perhaps we can drop support.  Unfortunately, <marquee> is written in XBL, so I'm not sure how to do use counters.

I rebased the patch and moved the atom declaration, I double checked that this collects events in about:telemetry;

1. load:
data:text/html,<body bgcolor="whyisthisacolour?"><marquee id=m loop=1 scrollamount=90 onstart="a"><iframe src="" height=500 width=500 scrolling=no></iframe><script>["start", "bounce", "finish"].forEach(e => { m.addEventListener(e, (...args) => {console.log({[e]: args})}); }); m.stop()</script>
2. open about:telemetry
3. click histograms
4. select "content"
5. filter "counter2"

Does this need anything else to land?

Would you mind filling out the data review request form ( and attaching it as a .txt so that you can r? me on it?

It should be pretty straightforward since you already have a clear question you want answered (are there a lot of websites using these).

1) Is there or will there be **documentation** that describes the schema for the ultimate data set available publicly, complete and accurate?


2) Is there a control mechanism that allows the user to turn the data collection on and off?

Yes, telemetry setting.

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

Yes, Jonathan Kingston.

4) Using the **[category system of data types](** on the Mozilla wiki, what collection type of data do the requested measurements fall under?  **

Category 1.

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

Default ON.

6) Does the instrumentation include the addition of **any *new* identifiers** (whether anonymous or otherwise; e.g., username, random IDs, etc.  See the appendix for more details)?


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


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

No, permanent.

BTW, if you rename the form to .txt, it's easier to review since it gets displayed inline in Bugzilla.
