bug/feature request: remembering history

[Rik44444]

hi, thanks for this addon, brilliant. I have 1 niggle: whenever i access a youtube page and your addon redirects it to Invidio.us, i can no longer press "back" any more in the browser, it's like the history is forgotten. So this is a request to A) either make it so that the history remains, or B) add the option that the redirect happens in a separate tab, so that the original tab goes to youtube, and i can press "back" on that tab
