How secure is Facebook extension for Chrome?

 

I recently installed the facebook extension for Google Chrome. But how secure is it? Look at the 2 screenshots below.

When the extension was installed, my facebook home page was appearing in place of the Techcrunch on facebook badge. What if this happened on a public computer, say at an internet cafe?

Needless to say, I uninstalled the extension immediately. And to end, I wanted to share an article I read sometime this past week but I can’t find it right now. It came down heavily on Chrome for still having some basic loopholes, which other browsers learned long back. Kinda like you put some laws in place after the Great Depression of 1930 to prevent a recession in the future. But some smart people repealed the law (or gave exceptions to some firms) and voila – we have the recession of 2008! Lessons learned in the past have to be applied.
