AdGuard Browser Extension v4.4: improved ad blocking with AGTree integration

Day after day, we’re back here with new updates – we can’t help but constantly aim for a better ad blocking experience, it’s just who we are. But as much as we love to introduce new, exciting features, they’re not always the focus of our updates. That’s what AdGuard Browser Extension v4.4 is all about: while you may not spot any visible changes, rest assured, we've been working hard behind the scenes. Let’s take a look at what's new.

AGTree integration

This update focuses on enhancing how rules and filters are managed, all thanks to the integration of AGTree to the TSUrlFilter library.

AGTree is a powerful tool that streamlines how ad-blocking filter lists are handled. It's now part of the TSUrlFilter library that we've integrated into various products, including browser extensions. By implementing AGTree across different platforms, we're aiming for a more unified approach, which allows us to use a single library for tasks such as conversion, parsing, and validation of blocking rules. The result? Improved content blocking, faster filtering engine startup, and simplified rule analysis and conversion.

And how does this benefit you directly? Moving to AGTree enhances your security by minimizing the risk of filtering errors. This means a more accurate ad and tracker blocking experience as you browse. Additionally, along with the AGTree transition, this release includes significant updates to Scriptlets that ultimately boost the overall performance of the extension.

Other improvements

This version also comes with a long changelog with many bug fixes and other small improvements. You can check it out on our website. Besides, to guarantee a seamless implementation of AGTree in our extension, we have updated our Scriptlets and our filtering engines — TSWebExtension and TSUrlFilter.

Sharing your feedback on the new version and your suggestions for future releases is a great way to make sure we’ll keep working towards the perfect ad blocking experience for you. Reach us out on our social media platforms or on GitHub.
