[Conkeror] conkerer-xr pop up windows

[Brian May]

If I go to a webpage that displays a new window, the original window
disappears, and I can't get back to the previous page.

For example, if I click "Back to gallery" on the following webpage:

http://www.theage.com.au/cartoons/

Sometimes the new window won't accept keyboard commands, but I can't
reproduce this on demand.
