How do I prevent a website from opening another window

Firefox
krueger_industrial replied

A couple of websites I occasionally visit open up a second window to a spam website. I have put an entry in my Hosts file to prevent Firefox from connecting to the spam websites, so the second window is empty. However, it's still a little annoying.

I have pop-up blocking turned on. Is there anyway to completely block the opening of the second window?

If not, why not?

Thank you for taking the time to reply. I really do appreciate it.

Unfortunately, the link you posted tells me exactly nothing. My question is "How do I prevent a website from opening unwanted windows". These are full Firefox windows, just like you would get if you right clicked on a link and selected "open in a new window".

There are only two possible answers:

(A) To block unwanted windows, do this ________ (insert answer)

or

(B) It's not possible.

If the answer is (B) then the follow-up question is -- Why Not?
