Popup Blocker (strict) is a lightweight extension to prevent websites from opening pop-ups. The extension pauses all sort of window opening requests for user attention. You can either accept or deny a request. Multiple unique requests are shown in an array. 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.
Options:
1. Deny popup request
2. Allow popup request
3. Open popup request in a background tab
4. Redirect current page to popup URL source
Supported blocking methods:
1. window.open
2. a->target=_blank
