THANK YOU - maybe a best addon for firefox..... blocking popups on specific sites - brilliant idea

Hi, i'm on ff44, because it's the only one supporting all past addons that are still needed, i cannot update or i lose 10 or more addons functionalities. it would be nice if you could add compatibility for ff44.

Es la mejor aplicacion para bloquear ventanas no deseadas que se abran solas antes tenia una app en chrome pero cuando me cambie a firefox 57 es lo primero que necesitaba.

I was missing a white-/blacklist feature but I found it in the beta. Now it's perfect, except that it blocks the private-browsing-window...

Before I installed ( Popupblocker ) I had 2 Ad Blockers one which is Extremely Popular.
.
And MOST of the Time 2 Unwanted New Open Windows would get Through including that FAKE Annoying
( Microsoft has Found a Virus Please Call us )
.
But After Installing ( Popupblocker ) and w/o making ANY adjustments to it:
.
I INTENTIONALLY clicked on 45 Sites / Links I ALWAYS Had a POP UP / Unwanted New Window Problem with.
.
I even Persisted Clicking, and not a Single Pop Up or Unwanted Window Came Through NOT ONE!!
.
I can see The Instant FLASH of some of the Pop Ups / Unwanted Windows TRYING to Come Through but not a Single ONE eve did!!
.
I Noticed sometimes I had to Persist Clicking on a Button to get a Page I wanted but it ALWAYS went through ( mostly after 4-5 Clicks ) but that's a Perfect Price to Pay to avoid the bad Ones!!
.
So Far it FEELS to Good To Be TRUE, but so far it's TRUE!
It Works ( At Least for Me it dose! )
.
I STRONGLY Recommend Everyone to Test this one!!
.
I will be Posting This Review and Recommendation On My Facebook Help Page Were I help KODI / Movies and PC Users .

Es blockiert nicht nur, dass Webseiten neue Fenster öffnen. Sondern man soll sogar bestätigen, wenn man selber ein neues Fenster aufmacht, dass das neue Fenster wirklich gewollt ist. :D

The version 1.1.2 works fine.
Great work.
Thanks.
