User reviews

Malwarebytes Browser Guard is praised for blocking ads and enhancing security, trusted by Malwarebytes users. However, multiple users report Firefox slowdown, high memory usage, and broken functionality with ReCaptcha. The clipboard protection is viewed as intrusive, causing popups and modifying copied content. Some reports highlight issues with subscription status recognition and data permission practices that raise security concerns.

Pros

Effectively blocks annoying content and advertisements, enhancing browsing experience.
Provides good privacy and security options to protect users from malware and unsafe websites.
Trusted by users already familiar with Malwarebytes antivirus, adding confidence in its utility.

Cons

Causes performance issues such as significant slowing down of Firefox and high memory usage.
Interferes with site functionality, notably breaking ReCaptcha and requiring users to disable settings on some sites.
Clipboard hijacking feature causes annoying popups and modifies clipboard content excessively.
Issues with subscription recognition and retaining tab information after updates.
Optional data access permission is required for proper functionality, raising privacy concerns.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Malwarebytes Browser Guard requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Malwarebytes Browser Guard has earned a fairly good reputation and likely can be trusted.
