Support search by NOT using Omnibox

[mammuth]

The injection only happens when you browse to google.com/search?* by using Chromes Omnibox meaning that the script never gets injected by using google.de and start typing into the input field.

Maybe with a listener on the input field?

Might be helpful.
Also there is more than one "q=" clause in the URL, so maybe check that with lastIndexOf instead of indexOf.
