    PopUpOFF is an open-source[1] and non-commercial[2] extension for Chromium browsers(Chrome, Edge, Brave, etc.) and Firefox that allows the user to remove overlays, pop-up ads and other restrictions from the screen while browsing the internet.

    When activated, extension can work in 3 different modes:[3]

    - remove and block every overlay for current website

    - remove and block every overlay except headers and footers for current website

    - remove and block everything for current page


    PopUpOFF had become popular after it was reviewed in one Spanish speaking internet portal. [4] [5] [6] [7] [8] [9] [10]

    Mechanics [11]

    - Remove

    Once you activate any mode, script find all DOM current elements for position fixed/sticky/absolute(only in 1 mode) - adds to them unique attribute if they not hidden, then hides them all. It also check body and html tags to "overflow: hidden" - this style blocking you from scrolling while popup opened - and resets.

    - Prevent

    A lot of sites don't show you popups with spam from start. So part of popups can be appended to DOM, or styles can be changed dynamically. So there is MutationObserver API here. It allows you to track all DOM changes, including changing styles, new elements, event text change.

    Cons and pros [1]

    - Ultra-lightweight. Ultra-simple. Open source. Non-commercial.

    - PopUpOFF blocks all stuck to screen elements, not only popups.

    - It's still in development, so there are could be new futures and bugs.

    - It does not block content ad.
