Open Adblocker
What Open Adblocker is
Open Adblocker is a free browser extension that blocks ad and tracking requests at the network level and hides ad elements on pages. It blocks banner, pop-up, pop-under, and video ads, and its site says it can stop YouTube pre-roll, mid-roll, overlay, and banner ads before they load. For Twitch, it filters ad-delivery requests including video ads and on-page promotions. The extension can also hide many cookie banners and consent pop-ups, and remove social widgets such as Like and Share buttons. Users can allow ads on selected domains in the extension settings. The maker describes the project as open source and links to its public GitHub code. The Free plan costs nothing, with no subscriptions, paid tiers, or upgrades. It is browser-only and supports a single browser. The FAQ says it works after installation without configuration and can be paused or resumed from its menu. The privacy policy says it may collect browsing activity, pages accessed, browser type, IP address, and operating system. Some sites may restrict access or show notices when they detect an ad blocker.
