Malwarebytes Browser Guard review

Malwarebytes Browser Guard does more for free than any other extension here. Malwarebytes says it blocks malicious websites, phishing attempts and scam pages before they can do harm, and its Chrome listing adds tech support scams, hijackers and hidden cryptominers to that list. Credit card skimmer protection is the feature you rarely see elsewhere: it aims to stop thieves capturing payment details on checkout pages. On top of security, it removes ads, third-party trackers and cookie consent pop-ups, so most people will not need a second blocker. Content Control lets you block any site by URL, domain or IP address, and site-specific controls and allow lists handle pages that break. It runs on Chrome, Firefox, Edge and Safari and does not need Malwarebytes antivirus installed. Some heuristic and advanced phishing protections sit in the premium column of Malwarebytes' comparison table, which come with a paid plan from $59.99 per year.
