How does the website "minutesplease.com" close tab in my chrome window? <p>The website "<a href="http://minutesplease.com/" rel="nofollow">http://minutesplease.com/</a>" does something I thought was impossible - it closes a tab in my chrome (also without my permission!).</p> <p>How is it possible for a website (not extension) to close a tab in my chrome window? Up to this moment I was conviced the most a website can do is stop to supply me with packets. In which case I will only get a connection error, not a tab termination. Also, not only did it close a tab, it closed a tab that wasn't his own (!). The only connection between this website and the tab is that it was responsible to open it.</p>
