I tried few popup blockers, this one works fine.

It's really efective, thank you! However I'd like to know if there's a plan to add a blacklist function, since I currently only need this for 1 website and it's pretty annoying having to whitelist every other site (if there's a way to do this already in the settings please let me know and I'll happily change my review).
I also think the UI of the dialogue boxes could be improved, and would appreciate a lot a dark mode for the settings page.

not a fan of the new ui

Worked perfectly for me until today's update. I could not use my Roundcub webmail while this AddOn was installed, I had to remove it and everything worked perfectly after. There must be some conflict there.

It was working at first, then it suddenly decided to be globally disabled, despite the box for the option being checked. Now I have to manually turn globally enabled on and off on a website for the blocker to work again. Even then, once I leave that page or website it goes back to being globally disabled all over again. I shouldn't need to do that on a popup blocker.

So effective in catching those stray popups that the regular popup blocker would miss!

But I wish the popup blocked prompt had two "trust" buttons: trust the source domain, and trust the destination domain.

Simple and strict like it says! Very good!
Jeremy is the bomb! yeee

must have

On Android not working correctly.

This addon offers several options to handle popups, but....

1. Allow popup does nothing
2. Trust popup only works on second try
3. Open in background does the opposite

Just the deny and redirect buttons work as expected.

On windows no issues so far.

非常不错的插件
