I couldn't this to work. all I get is an alert with chinese text in it and a checkbox asking whether to disable further alerts from this extension. when trying to open or diff. perhaps this works, but some instructions please?? totally willing to re-rate if I had instructions.

didn't work for me, every page I attempted to use had the message "This page is not supported."

Appears to compare the HTML code line by line, as if you put two text editors side by side. Expectation was a smart DOM comparison. Also didn't regognize inserted lines. Downloading the HTML and comparing using any text compare tool did a far better job for me.
