AdGuard is a fast and lightweight ad blocking browser extension that effectively blocks all types of ads and trackers on all web pages. We focus on advanced privacy protection features to not just block known trackers, but prevent web sites from building your shadow profile. Unlike its standalone counterparts (AG for Windows, Mac), the browser extension is completely free and open source. You can learn more about the difference here.
AdGuard does not collect any information about you, and does not participate in any acceptable ads program. The only source of income we have is selling premium versions of our software, and we intend to keep it that way.
You can get the latest available AdGuard Extension version from the Chrome Web Store.
You can get the latest version of AdGuard Extension from the Mozilla Add-ons website.
Opera is basically a Chromium browser, but it maintains its own add-ons store. You can get AdGuard Extension from there.
The latest stable version of AdGuard browser extension is available in Microsoft Store.
We are blessed to have a community that does not only love AdGuard, but also gives back. A lot of people volunteer in various ways to make other users' experience with AdGuard better, and you can join them!
We, on our part, can only be happy to reward the most active members of the community. So, what can you do?
