This would at least save some code.

We have been sending deprecation warning for 7 years (bug 553917)

For details and discussion I opened https://github.com/mathml-refresh/mathml/issues/127

Blocks: mathml-core

There are more XLink attributes: “href”, “type”, “show” and “actuate”
I think we can try to deprecated all of them on MathML elements.

# Data Review Form

1) Is there or will there be **documentation** that describes the schema for the ultimate data set in a public, complete, and accurate way?

Yes, this will be documented in the probe dictionary: https://telemetry.mozilla.org/probe-dictionary/

2) Is there a control mechanism that allows the user to turn the data collection on and off? (Note, for data collection not needed for security purposes, Mozilla provides such a control mechanism) Provide details as to the control mechanism available.

Yes, this can be turned off in Preferences, by disabling Telemetry.

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

This is not permanent.

4) Using the **[category system of data types](https://wiki.mozilla.org/Firefox/Data_Collection)** on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1: Technical Data

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)?

No

7) Is the data collection covered by the existing Firefox privacy notice? **If unsure: escalate to legal if:**

Yes

8) Does there need to be a check-in in the future to determine whether to renew the data? (Yes/No) (If yes, set a todo reminder or file a bug if appropriate)**

Yes, in ~4 release cycles, we should check in and assess a renewal.

9) Does the data collection use a third-party collection tool? **If yes, escalate to legal.**

No

I'll take a look into this later.

Depends on: mathml-dom

IIUC, browser_contentAltClick.js forces alt+click to perform a save operation so it does not seem appropriate to do it with non-link nodes. But thinking more about it, I think we should just update the tests to use normal MathML link instead of XLink.
