Help With Autopagerizer And Or Auto Page Fixed

I have the Add-ons listed below, mostly I want to use them on Reddit as there are many pages to view.
I have tried with AutoPagerize and AutoPagerize Tweaked and Auto Pager Fixed. In the past one of the above worked and allowed me to go from page to page without clicking on next. Now none of them work. There does not appear to be webpage for any of these where I could ask for help. Hopefully someone here will help, thanks. SMR

 

AutoPagerize is a browser extension for Firefox, Chrome, Safari & Opera.
Which one do you use?

 

Sorry Eldon, I use FF 95% of the time, Chrome type, Opera even Vivaldi sometimes on a Win 10 OS, on an uptodate system. Only Win Defender and Malwarebytes active. The whole idea of setting "rules" seems to be beyond me as I'm a dinosaur. Thanks for responding....SMR

 

Help for this software is almost nonexistent.
But, have a look over here.

Eldon, Thanks again, downloaded Greasemonkey, scripts, another learning curve, without success. This add on along with Auto Page (fixed) worked with my small surfing habits in the past with Win 7, no luck since Win 10. I guess I'll have to click on "next" etc. Thanks again.....SMR

 

I'm guesstimating that the problem is probably using the software in Windows 10.
The author doesn't even say with which Windows OS the software is compatible.
Have a look at this.

Maybe this is a solution.

Eldon, followed instru. at "scraping.pro" F12, Console, could not add suggested insertion. You are great to keep at it for me. These ideas seem to be above grade level (Ha). Thanks again.....SMR
