Stay Focussd

We all spend too much time on social networking sites like Facebook and Twitter. Now this affects our productivity at work. Also it can turn into addiction. So to let you concentrate on your work and make less use of these sites, there's an excellent Google Chrome extension called StayFocusd.

All you have to do is to install this extension into your Google Chrome browser, you need to right click it and select "Options". Here you can set a timer for your social networking sites. So once you exceed the time limit, your social networking sites like Facebook and Twitter or for that matter any other site will be blocked.

The extension is highly configurable as you can block entire domains, specific subdomains, specific paths and pages and even specific in-page content like videos, games, images, forms, etc.
