Rated 3 out of 5 stars

AutoPager has great potential and really saves a lot of time because it starts loading ahead of reaching the last page.

However, the UI is a nightmare. I had a simple task: Keep it activated on a whole forum, but deactivate it on single posts (it kept loading the next ones which wasn't too helpful in a tree-like forum).
Site options are cryptic, hard to read (black/blue on dark green), and hard to hit with the mouse. The options dialog offers a LOT of buttons with no guide which button belongs to what. To do what I wanted to do I had to copy the whole set of rules for that forum and delete the one by comparing long URLs. The extension author already noticed and made the text of the copy button red. Still took me quite some time to figure out what to do – and I'm by far no novice.
AutoPager really needs a simple user interface that allows to disable the feature/rule for the current page from the context menu and not some unreadable HTML inserted into the page – and nothing more. With the current UI it's impossible for casual users to do anything.

This review is for a previous version of the add-on (0.4.2.1). 

Thanks for the feedback.
I totally agree with you.
I will continue to improve the UI.
