Panopticlick by EFF stated that Avast Secure Browser offered "strong protection against Web Tracking" and that the browser did not have a unique fingerprint (in both configurations). I decided to run tests using the default configuration and with all privacy features enabled. One of Avast's main promises is that Secure Browser protects user privacy better than other browsers.

While you won't see a five times performance boost when you compared it to Mozilla Firefox, it is an area that the browser does really well in. It is as fast as Google Chrome in benchmarks and that carries over to real-world usage as well. To sum it up: The performance of the web browser is excellent. The small score differences between Avast Secure Browser and Google Chrome are not significant expect the same performance in Avast's browser and Google's browser. The benchmark results show that this is indeed the case.

Enabled by default but requires that Avast SecureLine VPN software is installed on the Windows machine. Avast SecureLine VPN - integrates Avast's SecureLine virtual private network in the browser.

You need to install compatible software on the device to use it. Avast Passwords (disabled) - integrates with the passwords component of Avast security products.

Supports third-party filter lists, custom rules, and whitelists. Adblock - an ad-blocker powered by uBlock Origin.A quick check on secure://extensions/ (yes, Avast uses secure:// for internal pages and not chrome// or about://), lists a total of seven extensions of which five are enabled. Three extension icons are visible in the browser's toolbar that provide video downloading and ad-blocking functionality and a link to the new Security & Privacy Center. You will notice some differences though as well as Avast's browser comes with several built-in browser extensions. If you used Google Chrome in the past, you will feel at home right away as the interface resembles that of the browser. Avast Secure Browser is based on Chromium, the open source part of Google Chrome, Vivaldi, Opera and other Chromium-based browsers.
