Fenix: [Bug] Media auto play not blocked as expected

[sophiekuehn]

Steps to reproduce

Set up firefox to block media auto play.

Expected behavior

No more audio or video starting automatically when opening a website.

Actual behavior

Media starts automatically anyway.

Example german news page: https://www.chip.de/news/Windows-10-20H2-Grosser-SSD-Bug-ist-aufgetaucht_183061995.html?layout=amp

Device information

• Android device: Oreo 8
• Fenix version: 82.1.1

I can confirm this behaviour.

I considere this a severe security issue.

Web-pages have access to blocked features, services or devices of the mobile - this should never ever happen. What else slips through unnoticed?

We put a patch for it see https://github.com/mozilla-mobile/fenix/issues/8987, are you able to reproduce in nightly?

It seams to be fixed in nightly atm. At least with my example from above.

@sophiekuehn thanks for the report. Are you able to reproduce on nightly? I tested on it, and I wasn't able to reproduce, please let us know if the issue persist.

@Amejia481 i can't even reproduce it today in the regular build. Something needs to have happened on the example webpage itself. Yesterday the video was playing automatically on regular and nightly. Fancy.
