The best "auto pager" there is for modern FF, bar none.

And contrary to the lone 1-star review by Firefox user 13754958, I find the author very responsive, and the extension works very well.

all free DIY , with all my need

Works incredibly reliably

keep up the good work

Thank you. Your extension is excellent and very close to Autopager the very best of all time. Go in that direction.

This is the most feature-rich and flexible add-on for infinite scrolling. It handles tons of popular sites "out of the box", but most importantly, it allows very flexible custom setup for sites that are not handled automatically. And unlike some other extensions, Infy allows customizations via not only XPaths, but also CSS selectors and keywords. It may sound daunting at first, but A) it's not very complicated, and B) I don't usually need to worry about these things, since for most pages, everything just works.
Thank you for this fantastic add-on!

very nice addon seems to work very well , but i still no understand some options :) very thanks
