Rated 5 out of 5 stars

It doesn't work, please fix.

This review is for a previous version of the add-on (1.50.1-signed.1-signed). 

In what way?

I know it doesn't work for pages with iframes (scrollbars in the page itself). Is that what you're seeing? What site did you test it on? Fel freer to email me if you like... Thanks!
