On page load, compares URL to a user-created list. Closes tab/page if there is a match. Useful for websites like Kissanime, where all popups go through the same redirector website first, then to the ad. Go to Options > Load Defaults after install!

Features & Capabilities

Similar to a popup blocker. Downside is it is severely limited; upside is it is undetectable by any websites. Popup blockers prevent popups from opening; this add-on instead closes the window immediately after opening. Be careful to not add any patterns that will match Google, Yahoo, Gmail, Wikipedia, etc. In the Options page you can specify your homepage/newtab page; they will be protected regardless of what you put in the kill-list. You can also add a set of "default" websites that should give you good protection on Kissanime.

Is PopupKiller Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

PopupKiller requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
