Steps to reproduce:

I found this bug when I tried to use indexedDB as a file cache in my extension.

  1. Copy the code from https://gist.github.com/eight04/c432b082c4134420bc008b53b3720f6f
  2. Go to https://example.com.
  3. Press F12 to open the console.
  4. Paste the code and run.

Actual results:

The blob object is dead. Any operation trying to read the data will fail. Including webextension downloads API.

Expected results:

Deleting the instance inside indexedDB shouldn't affect the blob object. It works fine on Chrome.

Tested on Firefox Developer Edition v67.0b7.
