Rip page to new window in firefox

On the bookmark toolbar, right-click and select "New Bookmark..."

Under name, give your bookmark a fitting title, like, "Rip page."
Under location, enter the following code:

javascript:var x=window.open(document.URL, '_blank','width=800,height=600')

Or... just drag the following link to your bookmark toolbar.
Rip page.


Update on August 5, 2008:
I found the following works well for ripping a Google Docs page to a new window (former window closes as well.)

javascript:var%20x=window.open(document.URL,%20'_blank','width=800,height=600
,status=1,toolbar=1,location=1');window.close();

Rip page.
