User Reviews

I don't know how to write regular expressions and had no interest in learning at this point. It works just as well (unlike Block Site, for me). You just type the URL. Done.

Is Simple Blocker 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.

Simple Blocker requires a few sensitive permissions. Exercise caution before installing.

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.
