Rated 4 out of 5 stars

I like the addon. But I need to use space twice- first it scrolls down, then it opens next page. Toolbar button works fine. An option to load pages under the loaded page (like Autopager) would be great.

This review is for a previous version of the add-on (0.12). 

I will consider adding an (hidden) option so that pressing "Space" opens the next page directly instead of doing the default "Page Down". Concerning the Autopager-like option, the answer is unluckily a definite no. For some Javascript-heavy sites (such as wired.com or gametrailers.com), loading/displaying the next page/set of data may be very complicated to do (not to say impossible) without referring to workarounds (as Autopager does with its "rules"). This addon is intended to be simple to use and generic and will remain as such.
