Preventing a site auto closing a tab?

[shabbysquire]

Have a problem during template creation:

There's a site (Add**me**fast) that keeps opening a new tab when I follow somebody. I need to grab a value from the page (with actions designer) but the website then closes the tab quickly.

Is there a way to stop the tab auto closing?

It probably closes by script. So the only one solution in theory is changing script's data in DOM via action designer.
