Firefox-gemeenschapsforum

i want to block popups from website x. I found in the menu a place where I can block alle the popups, and allow popup from websites that I add. But I want it just the other way around. Alle the popups are allowed, except the ones that I add. In the menu I can only choose "permit/allow' and I can not choose 'deny'. I use the Dutch version, so I translated the item.

1) how can i do this 2) if not, can someone make a note that this will be solved in a later version?

Thank You
