This free extension for Chrome allows you to quickly copy the title of a web page, such as Facebook or Twitter. This is useful in many situations, such as when you're using the Facebook app, which shows a page title when you're on a profile, even if you aren't the page itself. 

When you install this app, it automatically scans the websites you visit and stores the results in your browser's database. You can choose to either use it automatically or manually copy the title of the page you want to copy it from. The extension is easy to use and does not take up much memory.
