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.

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.
