Screenshots is currently not working for me on Firefox Nightly & Release (both latest).
Clicking the screenshots button, i get an error in the console:
> Error: Missing host permission for the tab     undefined

There is no stack available.

I have tested this issue on Windows 7 x64, Arch Linux and Mac 10.12 with latest Nightly (60.0a1) build, but I can reproduce this issue only on Test Pilot and AMO websites.

@Georg, can you reproduce this issue on any websites or Screenshots is not working only on some specific websites?

Ah! I was using this on a chrome page, specifically about:telemetry.

Thanks for the ping. Yup, about: pages aren't accessible to page actions. Github issue 2978 hides this error from users, but the error still appears in the console. I can't dupe to Github, so I'll just mark it as incomplete.

Can we make this more clear in the UI then?
It was surprising to me that the screenshots button is available, but doesn't result in any action.

Sure, I think the right fix would be to disable the page action on non-http(s) pages, and it seems like this would be easy enough to do.
