Thanks for filing this issue.

I can replicate this issue in Release 63, but not in Beta 64 or Nightly 65 on Mac. Given this and that the overlay is an iframe, I'm thinking the root cause is the same Firefox bug from #237 , as the fix for that landed in 64.

In this case the iframe looks like it's being unloaded, and perhaps browser.webRequest.onCompleted(from the fix for #237 ) isn't catching it? The URL between the different UI interactions doesn't appear to change, so I don't think it's a re-extraction issue...

I have retested this issue on Beta 64.0b11 and Nightly 65.0a1 (Build ID 20181121220101) and the issue is not reproducible, it's only reproducible on Release 63.0.3.
I will edit this issue for tracking purpose and also I'm sorry for misleading you on this.
