Working so well so it blocks browser's new windows called by user itself.

Exactly what I needed. It catches all the new windows and tabs a lot of scummy/annoying sites love to force open, despite how settings are set.

Thank you soooooo much. At most all I have to deal with is a white flash that's over in the blink of an eye. Much better than new windows/tabs.

Bonus points for a 20s timer option so I don't need to turn it on/off wholesale.

Great work Joof. Clean, adaptable and elegant.

catches popups that ublock misses!

FINALLY ... a popup blocker that works! I'm just using the "Smart Light" mode and it's blocking the popups without hindering the rest of the pages that I want.

It's the best popup blocker I've used so far and it catches unwanted new tabs also which great, I've seen junk sneak through that way before.

its acctually works unlike the other bullshit. Well done Joofthan

One of the best popupblockers for firefox ! Just because he can block - new tab -, that makes it very effective adblocker. It completes with strict popup blocker. Cheers for developer.

Has ALL the features that are missing in "Strict Pop-Up Blocker" including whitelists

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
