Rated 5 out of 5 stars

I resolved my problem. My about:addons page contained 2 copies of "AP-fixed to 0.8.0.10.1-signed" in it.

I disabled the one that said: "AutoPager is a Firefox/Mozilla/Chrome/Opera/Safari/Fennec extension to autoload the next page(s) when you scroll pages."

And left the one that said: "AutoPager Fixed is a fixed version of AutoPager extension for Firefox 36+ (non-E10s mode) to autoload the next page(s) when you scroll pages."

I haven't made any changes to FireFox in years, so it must have been something Mozilla did. Plus, version 38.0.5 is not accessible to the users yet.

Thank you for your very prompt reply! I truly appreciate your effort & time!!!

I absolutely LOVE the Autopager-Fixed plugin, since I started to use the original AP plugin about 3 years ago. I can't live/surf without it! AP is a God's send!
It was working this afternoon, but now it's not. I'm using FireFox 38.0.1 on my Mac Mavericks and I see the about:addons page was last updated today (or maybe that was with regard to the comments last posted). Can someone please fix AP again? I wish I knew how to fix it myself (sigh). I'm trying to learn XPath, etc.
Thank you!!!

Update AP-fixed to 0.8.0.10.1-signed
Update Firefox to 38.0.5
