Recent reviews
Ever since I installed this extension, Firefox has become horribly slow. Basically, it slows down the performance of other extensions (especially email management ones). As soon as I uninstalled it, Firefox went back to normal.

Today's update broke the extension. It now blocks any link from Google, and you cannot tell it it to continue or allow the link.

Is Malwarebytes Browser Guard Safe?
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 a lot of sensitive permissions. Exercise caution before installing.
