Hey raki, Could you please take the following steps to help us troubleshoot the issue? # Open a new tab and enter ''about:logging'' into the address bar. # Set the Logging preset to ''Media playback''. # Click on the ''Start Logging'' button. # Reproduce the issue: go to the website where the problem occurs, play the media and trigger the bug to happen in the browser. # Once you've captured the issue, click on the ''Stop Logging'' button. A new tab will open with the Firefox Profiler information. # In the top right corner of the Profiler page, click on the ''Upload Local profile'' menu. In the dialog that appears, tick the check box next to '''include hidden threads''' and then click the ''Upload'' button to submit the log. # Copy the profiler link (it usually starts with https://share.firefox.dev) so you can share it with us.
