Is SiteBlocker: Easy Blocking and Scheduling 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.

SiteBlocker: Easy Blocking and Scheduling requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
