On Pace od Michael Savych

On Pace is the ultimate tool to help you stay focused and eliminate distracting web resources. With this extension, you can quickly block websites that you want to restrict access to.
Easily add websites to your block list with just a few clicks. You can choose to block individual pages or entire domains, ensuring you're only browsing content that aligns with your goals. The extension also introduces a “strict mode” – a feature that allows to temporarily unblock chosen URLs, and automatically block them again after a certain period of time. The feature adds an additional restriction layer for people who require a more rigid control over their Internet surfing habits.
On Pace focuses on simplicity, which result in an ability to perform any operation in just a couple of clicks.
To start working with the extension, simply click on its icon in your browser or use Ctrl+Q keyboard shortcut.
