It does happen to you when you visit a webpage which doesn’t offers clickable links for URLs and email addresses for example like http://techdows.com or venkat@gmail.com to open them in new tab page, what you will do is simply copy and paste text for the URL or email address manually into the address bar or into related applications, isn’t it annoying, Clickable Links extension for Chrome turns unclickable URLs (http:// ,https://,ftp://) and email addresses into clickable ones.
