If you use Google Chrome and don’t use extensions, then you should probably give them a try.
They’re useful or interesting programs you can add to your web browser that provide new features, or block parts of websites that annoy you. They allow you to customise your internet experience.
To add them, head to the “wrench” menu, then click “settings”, which will take you to the settings menu.
Once you’re in the settings menu, hit the “extensions” option on the left hand side. Finally, click on “get more extensions” and you can search for whatever extensions you need.
