Might use onHistoryStateUpdated. See Chrome docs and MDN docs.

As mentioned in 0533304,

Also, I need to implement some way of resetting the stored values when a
new video is in use. It could be just tied to the DM logo. I could also
store the URL and clear the session storage every time the URL changes.

But you still have the issue where the video is mirrored, you open a new
tab and run DM there, come back and the video is still mirrored but the
extension doesn't show that. I don't think that's too bad of a
situation, though.

onHistoryStateUpdated seems like an cleaner solution (from the perspective of the user), but it might require more invasive permissions.

I think all of the session storage should be cleared and the content scripts wiped clean. That means

• disconnect the observer
• reset playback speed
• turn off looping
  This could become a hassle if more features are created, so keep that in mind.

For now, I'll tie this to the DM logo.

It'd be useful to tie each DM page to the browser tab, though. Once the tab closes, the state would be cleared. I wanted to originally do this via the browser's sessionStorage property, but that would increase complexity by messaging between the extension page's background scripts and the browser's content scripts (eg. loading the values of the checkbox in the extension based on the value in the browser). It'd be more accurate, though.
