What is Poper Blocker?
Poper Blocker is the first dedicated pop-under blocker that blocks all these annoying popups and popunders that pop no matter where you click on a page.
How to use it?
It’s very simple. Just install Poper Blocker and from that moment on, any time a new pop-under or pop-up window is about to pop, it will be automatically blocked and a notification will be shown.
You can view the blocked content by clicking on its link in the notification.
“Allow always” will suppress the blocking of any future content generated by the current website and add it to the whitelist.
The whitelist can be managed by the extension’s options page.
Please spread the word by joining Poper Blocker’s social pages!
Is it free?
Absolutely yes!

Thank You.
Could you fix Depositfiles please? Using chrome
Hey guys, this add-on works very good in chrome, and it will be awesome if you could make a version for Safari. Thanks
When will there be a new version for Firefox. Google chrome is on version 1.86 while Firefox still has version 1.62 ?
Now! 🙂 updated the FF version to v1.91. You have to update it manually by downloading the new file and drag it to the FF window.
it would be really helpful if you could also make this available to opera
You did a great job with this APP, I hope you don’t stop supporting it, and whatever you do, don’t fall to Mozilla, that means, don’t make it Open Source.
I’ve tried poper blocker on Chrome an works flawlessly. I want to try the Firefox version but I can’t find it listed on the Mozilla add-ons page. Why is that? I do know how to install an .XPI, it’s just that I find it odd.
Poper Blocker doesn’t contain an open sourced code, to make it hard on spammers to bypass the protection, but it also makes it hard for Mozilla to approve my extension for the same reason.
That’s why Poper Blocker is only available through here. You can download the XPI and drag that file into your Firefox browser – the installation process should pop.
Please make a update of firefox verision. It’s not compatible with the newest version of firefox. Thanks
FYI, the big isreli agencies (sekindo etc) sow popups again
Not any more. Version 1.72 fixed this issue.
Thanks!
