JustBlock – Ad & Popup Blocker

Block intrusive ads, unwanted popups and trackers. Free core protection with optional Max Clean page cleanup.

Browse with fewer automatic popups and fewer common tracking requests. JustBlock starts working when you install it. Core protection is free. Max Clean is an optional yearly upgrade that hides distracting elements on the page. If a site needs to keep working, you can add it to your trusted list or pause protection from the popup. POPUP PROTECTION JustBlock watches windows opened by scripts. It blocks popups that open on their own, very small windows, and windows placed off-screen, which is a common pop-under trick. It also blocks popups whose address matches known popup-ad networks. If you have just clicked the page, a window opened from that click is left alone, so signing in or paying can continue. JustBlock does not recognize a window as a login or a payment. It uses your recent click. You can pause Popup Guard, or trust the current site, when a website needs a window that protection is stopping. TRACKER FILTERING Built-in rules block listed email-tracking pixels, Facebook tracking endpoints and cryptominer scripts. That reduces some tracking requests while you browse. These rules do not remove every banner on the web. Sites can still show ads that are not covered by the bundled lists. LINK CLEANUP Open JustBlock on a page and clean the address when you want to. JustBlock removes common tracking parameters, including utm tags, fbclid and gclid, and reloads the page. Link cleanup does not run on every link in the background. TRUSTED SITES Add a domain to your trusted list and JustBlock skips it. You can also pause all protection from the popup and turn it back on when you are done. OPTIONAL FILTERS These stay off until you turn them on: • A short list of reported scam domains • Clickbait recommendation widgets • Adult-site domains • Search-redirect domains Turn a filter on only if you want that extra blocking. The scam list is a small bundled set of reported domains, not a live phishing scanner. WHAT YOU SEE IN THE POPUP The activity list is stored on your device. It shows recent events such as a popup stopped, a site you trusted, protection paused or resumed, and a link you cleaned. It also counts popups stopped today. It does not scan every page you open, and it does not raise phishing alerts. LIMITS Results depend on the website and on the rules included with JustBlock. JustBlock does not read the page to detect phishing, warn you before you type a password, scan downloaded files, or remove malware from your computer. It is not antivirus software. MAX CLEAN — OPTIONAL YEARLY UPGRADE Max Clean hides distracting elements inside the page. It can cover: • Cookie notices and signup overlays • Floating video panels • Floating chat widgets • Other elements you select yourself Hiding a cookie banner does not accept or reject cookies for you. Privacy masks only cover areas you choose. They do not erase the original page. Free popup protection, tracker filtering, link cleanup and trusted-site controls stay available without a subscription. PRIVACY Filtering and page cleanup run on your device. Core protection does not need an account. JustBlock does not upload your browsing history. If you buy Max Clean, payment and subscription services process the information needed to charge you, activate access and manage the subscription. These features do not send the addresses you visit, or the contents of pages, to the billing service.
