ProBlocker review
A free, open-source browser blocker with strong YouTube coverage and limited platform reach.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ProBlocker is a free, open-source browser extension for people who want broad ad and nuisance-content blocking without an account, subscription, or paid tier. Its strongest fit is Chrome users focused on YouTube, where it targets pre-roll, mid-roll, overlay, and bumper ads. It also blocks trackers, analytics requests, pop-ups, pop-unders, forced redirects, overlay dialogs, known malware domains, scam endpoints, and cryptocurrency-mining scripts. Network-level filtering happens locally before ad requests download, giving the product a focused privacy and page-cleanup role inside supported browsers.
The pricing model is straightforward: ProBlocker is free, and there is no paid tier to compare or upgrade to. Its filter lists are compatible with EasyList rules and update automatically, while manual update controls provide a direct way to refresh them. The vendor states that the extension collects no browsing history, URLs, analytics, or telemetry. That combination makes ProBlocker a practical choice for users who want local blocking and do not want to manage an account or recurring payment. It is less suitable for buyers specifically seeking paid support, premium controls, or a tiered feature set.
Platform reach is the main constraint. ProBlocker is delivered as a browser extension, with support listed for Chrome, Firefox, Edge, Brave, Opera, and Vivaldi, while Safari is unsupported. It does not extend to desktop or mobile applications, so it cannot serve as a device-wide blocker outside the browser. Choose ProBlocker for free browser-based blocking, extensive YouTube ad coverage, automatic filters, and a no-telemetry approach. Choose another option if Safari support, broader device coverage, or more verified customization features matters more than open-source local filtering.
