Doesn't send cookies with the request

This is a cool project!

I want to use this extension in a site, where we use authentication cookies. When I turn the extension on, it sends the request, but the Cookie header is missing, so my auth cookie not sent to the server.
If I open the URL in a separate tab, there is no problem with it, Cookie header is there.

I have to admit I hadn't thought about that. I haven't touched this codebase in quite a while, but I'd be open to a PR if you want to take a crack at it.
