    if (details.url.includes(url)) {
So, if I want to detect if you have this plugin installed, I load an image with ?plugin-test=wsj.com as any part in the url can have it to trigger.

If you add this to the manifest "permissions" section and go to http://pbb.nkcss.com/ you can see it's easily detected:

    "http://pbb.nkcss.com/*"
And if I can do it in a few minutes, I'm sure those who have a paywall can do so as well.
