Not effective. Seem to be getting just as many popups as I did before installation.

I send daily reports to this creator. Daily! Each report details the next website that gives me popups. Strict blocker? I think not.

I don't know how this works for normal pop-ups, because I already have a extension that blocks them. but I wanted one to block annoying ones that open a new tab every few times I click on a html5 player to choose a control. this add-on did not do anything more than my old one did from another author.

Every time I try to add it, or Facebook blocker, it invites me to download Firefox for the 43rd time

Doesn't work on many pages.

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.

Yes it's strict - enough to break most web pages. If that doesn't bother you perhaps getting a prompt on every single web site you visit might. It bothered me. I found it far too invasive to be practical.

Installed to block one nasty site. It failed. Otherwise was working as expected until I found that it blocked my banking website. Despite whitelisting the domain (citi.com) and everything else I could try, the only recourse was to disable the add-on.

Funktioniert leider überhaupt nicht.
