Details

If I try to use "insertCSS" from within a "onUpdated" listener, then the call fails.
If I do so, I get the following errors on browser console:

Error: No window matching {"all_frames":true,"matchesHost":[]}

Source is "(unknown)". Maybe some dynamically created javascript?

Idea was to get the CSS to survive browsing in the tab or reloading the page.
This means that you don't have host permissions from the page you're trying to inject into.

Thank you. This did the trick. Is there already a bug which handles "better error messages for WebExtensions", where I can put myself on the CC list?
