Inject the autocomplete before page has loaded

[vladnero]

Sebastian, my friend! You said: "Nothing much I can do, if the page hasn't loaded yet, I can't inject the autocomplete.".
You can add:

"run_at": "document_start"

in "content_scripts".

See description here: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/manifest.json/content_scripts

Tried that, doesn't change anything...

If you really want to run some script before the rest, you have to run it inline:

var actualCode = // Content of scripts/inpage.js here;

var s = document.createElement('script');
s.textContent = actualCode;
(document.head || document.documentElement).appendChild(s);
s.remove();

Ideally, your build script would read scripts/inpage.js, serialize it to a string and put it in the actualCode variable. But if inpage.js is just a few lines of code, then the above can be used.
