Pretty impressive extension overall. It is the only security extension that I have found so far that protects against trackers/ads, PUP's, malware, and scams. On one website alone it blocked 478 Ads/trackers, no joke. The reason for only giving 4 stars is that I wished it communicated with my Malwarebytes desktop application as well. As far as I can tell it does not. When the browser extension says it blocked malware I wished it showed up in my desktop applications protection results as well to show an overall security posture result that Malwarebytes is providing me. Overall very impressive I recommend.
