User reviews

Malwarebytes Browser Guard offers robust security features, effectively blocking malware, ads, and spam. However, users report significant browser slowdowns, memory issues, and compatibility problems with sites using ReCaptcha and major email platforms. There are also inconsistencies in global filtering settings and challenges recognizing premium subscriptions. Additionally, Firefox's slow approval of updates delays new versions reaching users. Overall, while it enhances security and privacy, performance and usability issues diminish the user experience.

Pros

Provides strong privacy and security features, including blocking malware and unsafe websites.
Effectively blocks ads and spam, improving browsing experience.
Allows users to override security warnings to access sites if needed.

Cons

Causes significant browser performance issues including memory leaks and slow loading, especially with multiple tabs or when certain protections are enabled.
Interferes with functionality on legitimate sites that use ReCaptcha and email services like Outlook and Gmail, requiring disabling protections to use them properly.
Subscription and premium features are not always recognized correctly by the add-on.
Global settings for malware and scams filtering behave inconsistently across tabs.
Users face delays in receiving latest version updates due to Firefox's extension approval process.

mb browser guard after latest update, does not keep saving the 3 tabs (ads, malware and scams) in the tab current website..uninstall or clear cache doesn't fix it. Except this, it doesn't recognize my premium subscription (device security is installed but it says upgrade to premium)
