Answer 1

You should look at the source for the pixel perfect extension as it does something similar to your ( somewhat vague ) description:

Answer 2

You can use 'window/utils' SDK API and its openDialog() function:

require('sdk/window/utils').openDialog({
  url: 'http://stackoverflow.com',
  name: 'My pop-up window!',
  features: 'height      = 180, ' +
            'width       = 320, ' +
            'toolbar     = no, ' +
            'menubar     = no, ' +
            'scrollbars  = no, ' +
            'resizable   = no, ' +
            'location    = no, ' +
            'directories = no, ' +
            'status      = no'
});

This API is described here: https://developer.mozilla.org/en-US/Add-ons/SDK/Low-Level_APIs/window_utils
