The Bugbug bot thinks this bug should belong to the 'DevTools::Console' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hello,

I reproduced the issue using the provided add-ons on the latest Nightly (89.0a1/20210322174641), Beta (88.0b1/20210322185611) and Release (87.0/20210318103112), with additional checks on Release 86.0.1 (86.0.1/20210310152336) under Windows 10 x64 and Ubuntu 16.04 LTS.

Using youtube-musical-spectrum-1.4.3, the visualization is not working on either of the tested versions, however, the 'Error: permission denied to access object script.js:501:29' error is only displayed on Release 86.0.1 and Release 87.0. On Beta and Nightly the error does not appear in the browser console.

Using youtube-musical-spectrum-1.4.3-workaround, the visualization is now properly displayed and working on all of the tested versions, the error not appearing on either one.
