1805319 - Microphone permissions request does not display if gUM called from a redirected iframe

Status: RESOLVED FIXED

(Firefox :: Site Permissions, defect)

Description

[Mitch Talmadge]

Attachment: Screenshot showing results of running example 2 in the provided jsfiddle.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:107.0) Gecko/20100101 Firefox/107.0

Steps to reproduce:

1. Build a webpage that calls getUserMedia (gUM) in order to get just the user's microphone.
2. Build another webpage (I believe it needs to be on a separate domain/subdomain) which does noting but redirect to the first page.
3. Build another webpage which includes an iframe with microphone permissions, and a src linking to the second page.
4. Upon loading the third page, expect to see a permissions door hanger asking you to grant access to your microphone.

Actual results:

The permissions door hanger never opens. The gUM promise will stall and never resolve or reject because the user has never responded to the request. A microphone icon is shown in the chrome, where the door hanger should be, but clicking it does nothing.

This can be reproduced by running example 2 in this jsfiddle I created. I used TinyURL to simulate a redirect to an otherwise working example:

Expected results:

A microphone permissions request door hanger should open, asking the user to allow access to their microphone.

Mitch, thank you for reporting thing and providing an excellent reproduction! This turned out to (un)fortunately be a simple typo in the message identifier in the FTL file.
