AFAIK, Narrator does not officially support Firefox yet. They need to use what they call an UIA to IAccessible2 bridge to get all the information they need from Chrome and Firefox, but thus far have only officially documented supporting Chrome. Narrator does not seem to recognize that these panels now use a document'ish interface. One could try pressing NarraotKey+Space to force Scan mode (what they call it), but since the UIA to IA2 bridge probably doesn't work in Firefox yet, this is very like to not work.

Again, Microsoft does not officially support Firefox with Narrator, so there are expected to be bugs like this that other screen readers that do support Firefox, don't exhibit.

Ok, thanks, that's, uh, a P3 then? Not really actionable for us at this point but would seem strange to just close it, too.

Priority: -- → P3
Component: Tracking Protection → Telemetry
Product: Firefox → External Software Affecting Firefox
Version: Trunk → unspecified

The product::component has been changed since the backlog priority was decided, so we're resetting it.

Priority: P3 → --

Wrote to our discuss list with Microsoft and got this answer from Gov.

You would just need to implement the UI Automation provider:

So, it might be actionable for us after all.

Ah, thanks for getting in touch with them, but that seems like something the a11y team would need to build and maintain, not something for security engineering.

Janet, I'm not sure why you moved this to Telemetry, but I'm moving it back to Firefox.
