Sounds like a good idea, but in practical use, it's not. For casual browsing, I guess it is probably useful, but for everything else, it just messes up. At work, I access documents on-line, which are opened as pop-ups (yes, it's stupid, but that's how it was designed and there is absolutely nothing I can do to change that and, because it's work, I have to deal with it, and for a good part of my day). White-listing my work's site didn't work, neither did the forceful open option (the pop-ups opened blank, because they were, actually, redirects from the add-on, so the site didn't trust them and, therefore, the access was denied). In the end, it caused more troubles than occasional pop-ups would.

Hasta el momento cumple con su función. Gran trabajo!

doesn't work on youtube

Disappointing as it will not remember to deny sites you already denied.. so I have to deny 2-3 times for a single site. Not well written it needs to remember sites for denying.

It does'n work against "exit intent popup", so it's almost unuseful.

This Is SO SO SO SO SO AWESOME !!!

Bastante eficiente no bloqueio de popups indesejados. No entanto, podia ter um design mais atual...
