About this extension
Time Lock Blocker is a productivity and self-control browser extension that blocks access to user-selected websites for a fixed duration.
Once a block session is started, it cannot be cancelled or bypassed until the timer expires.

The add-on is designed to remove impulsive decision-making by enforcing a time commitment rather than relying on willpower.
