popup will auto close when lose focus.
you can use panel instead.
chrome.windows.create({ url: 'http://mobile.google.com', width: 320, height: 480, type: 'panel' })
It will keep opening across all tabs.

This is impossible, the popup will always close as soon as it loses focus.
If you need an always visible UI, your only option is, probably, injecting it into all pages.
