No, I don't know any extensions either. And as people were talking, it seemed there were none.
Most sites that care now don't employ horizontal scrolling - much.
In my other browsers I have to - time to time - zoom out or scroll to see if I miss something on the right...
Well, I guess the codes are developing, thus one day we might not need elaborated tools to fit a page to the width of the window... Maybe... In terms of sniffing what display we're using, feedback from the browser about the current window width perhaps, kinda...
