The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Hi Asaad, thanks for the report. Unfortunately, I am not able to reproduce this either on my MacBook or my Ubuntu machine. One way to find out what's wrong is to get the program logs directly. Can you follow the instructions below to help us get the logs?

1. Install Firefox profiler: https://profiler.firefox.com/
2. Open Firefox, and go to about:logging page
3. Click Logging preset and choose Custom
4. Clear the New log modules text field and enter Autoplay:5, then click Set Log Modules
5. Click Start Logging
6. Open a new tab and repeat the steps that produce the autoplay problems. Once you reproduce the issue, close the tab, then go back to about:logging page and click Stop Logging
7. The Firefox Profiler should launch itself automatically.
8. Click Upload Local Profile, you can choose to download the profile and upload it here as an attachment, or upload it and share the link here.

The tutorial to get the logs is here: https://paul.cx/public/about-logging-presentation.webm. Once the logs are obtained, we can have a further look into this issue.

Thanks for the efforts. However, we need a profile that recorded the bug to investigate this issue.

I am going to close this right now. Feel free to reopen it once you are able to record a profile with this issue.
