Popup Blocker (strict) od Jeremy Schomery

Popup Blocker (strict) is a lightweight WebExtension to prevent websites from opening popups. The extension pauses all sorts of window opening requests for user attention. You can either accept or deny a request. Multiple unique requests are shown combined. If a website requests a single URL more than once, a badge number will be shown indicating the total number of requests to this particular URL.
