Features & Capabilities

FocusBlock is a powerful productivity extension that helps you stay focused by blocking distracting websites during work sessions. With three preset focus modes (Work, Study, Deep Focus) and a built-in Pomodoro timer, FocusBlock makes it easy to eliminate distractions and maintain concentration. Each focus mode comes with pre-configured blocked sites, or you can customize your own list. The extension uses Firefox's webRequest API to intercept and block access to distracting sites, redirecting you to a friendly reminder page instead. The Pomodoro timer helps you work in focused 25-minute sessions, automatically activating site blocking when started.

Is FocusBlock 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.

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