Does what it should - blocks a lot of unwanted popups without calling those most annoying messages 'Disable your adblocker or you won't see anything'.
However when I want to open a new browser window (via it is quite annoying this also gets handled as 'unwanted popup'. I have to disable the popup or at least the 'block new window' feature to get my second browser windows. I consider this a bug that should be ironed out.

I use a mac version of firefox if that matters. This add-on would get five stars, but it prevents you from opening new windows on your own. If I tell firefox to open a new window it just closes immediately. I have to temporarily disable it in order to open a second window.

I would like to be able to copy-and-paste the address into the Black List. I have some pop-ups that are full screen only, and I cannot get to the icon to choose Add to Blacklist. Other than this, I like the blocking ability, especially when watching streaming videos.

Thanks

Bester Popup blocker den ich je gefunden habe! Für meine zwecke top und macht add ons wie Origin ad block blabla bla obsolet!!

The blacklist and whitelist constantly empty themselves after I add an entry to either of them.

can't stop me now

The best pop-up blocker you can get!

FANTASTIC, EXACTLY WHAT I WAS LOOKING FOR! THE SMART LIGHT FEATURE IS PRETTY SMART TOO.
THANK YOU SOOOOO MUCH DEV

Blocks everything thrown at it so far. Even blocks new windows (Finally a single instance add-on!!!). All other popup blockers have allowed pop-unders. Works perfectly with ublock origin.

White and Black lists are also included.

Many Thanks for developing the best blocker available.

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

* Error: Blocks all new windows, even when clicking "open link in new window" or opening a new window from the Firefox main menu! (if enabled global)
* Good to use by putting certain sites on the black-list.
* Minor: When a pop-up was blocked and I click "allow once" via the add-on symbol, it does not open the pop-up, but starts the "all pop-ups allowed for 20 seconds" countdown. If that is what the button does, why change its label to "allow once"?

Result: Simple add-on. Still helps. Will continue using.

* Idea: Implement per-host settings
* Suggestion: Option to block pop-ups / tabs from other hosts than the current

I've tried 5 popup blockers since Mozilla forced this update on us and my old one stopped working. This is the only one I've tried that actually works and has so far blocked 100% of popups on video sites absolutely rife with dodgy popups.


However it is unfortunately a little... too effective and will disable your ability to right click to open new tabs or windows unless you whitelist those sites or click allow after trying to open it - neither of which are overly practical for normal browsing habits. So it definitely needs to be improved to be able to tell the difference between deliberate user actions and automated popups. I've ended up setting it to allow all new tabs but block all new windows since most popups are new windows anyway and I rarely right click and open in new window instead of new tab.

It's a bit of a compromise but it works. Frankly I'm amazed that Mozilla would force an update disabling out of date addons and still not include a popup blocker that actually works as a base feature of the browser. The very first popup I saw on a video site after updating Firefox and losing my old blocker was obvious malware disguised as a Firefox update with a page that could not be closed due to dialog popups and it is easy to see how people could be caught out by something like that. This add on makes the internet safe and usable once again...

EDIT: I've just noticed that with 'Block new windows' checked I can't even open a new instance of Firefox from a desktop icon without temporarily disabling the blocker. With it turned off nothing is blocked even when set to 'smart'. I don't know what smart is supposed to do - as mostly it will allow me to open new tabs with middle mouse or right click menu but every now and then it will prevent me doing so forcing me to turn it off. Really needs some improving.

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 .

Version 2.0b2 is ok, good things white and blacklist.
Only one little problem: not all popups are blocked when I set "Allow all new tabs" and I put a website in the blacklist. Some popups of blacklisted website open

It is nice but I unintalled it because crashes when I make Firefox work with 4 processes.Please solve this

It not as good as the one I had before I reinstalled my OS and made a backup of wrong FF folder – it's damn slow and lets all popups open, but closes them a second later, so it does its job as intended. For me good enough, if dev will manage to actually block popups then it will be delightful.
I'm not sure though if „block all tabs” settings should prohibit user from opening anything, even if it's clearly at his will (like opening bookmark or new tab at all). I guess all really means all here, heh.

Could you add the option to block the popups instead of opening and closing them? Or could you make the closing be instant? The windows specially take a lot of time and the tabs make the screen blink. Which is annoying for sites that try to open a new tab almost every time you click.

Could you add the option to allow all popups except for pages on the blacklist and the blacklist to have the option to block tabs, windows or both?

EDIT: Thanks for your response. Would be nice to maybe create a github so people can leave you suggestions or bug reports there.

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
