The description of Validity - Play With New Friends
Validity is a cute extension for Google Chrome that will help you validating the HTML code of any website just clicking the icon appearing next to the address bar.
It will take no more than five seconds to tell you if the website is perfect or if it has any error.
If there is any error you'll have to go to the javascript console.
Validity can be specially interesting if you want to know the status of any certain website.
