PopupKiller

PopupKiller

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!

Summary

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.
