How does this differ from the native "More" link that is already there?

That depends on the Add-on. The management page you see when you click "More" includes some simple about-information, and may contain settings, donation links, and update settings. The About dialog, which About Add-ons adds a button to access, contains credits such as authors, contributors, translators, and the like, as well as their websites. It can also contain whatever information the Add-on developer chooses to include.

Nice to be the first one to comment about this add-on. It only add an about-button next every add-on in your list and that can be convieniant. I can not live with the "New Chrome-Firefox" so I am using the "old" FF 52.6 (or 7)->ESR<- for ever en ever till it dies :-) Intelligent readers do understand this :-)So I am moving to PaleMoon but this wil take many weeks to get al the "nice old customizations" working again. Maybe, the "old Firefox" / PaleMoon e.o. has a few minor disadvantages, hm.. it it 0,2 sec. slower yeahyeah..,sometimes use more memory, eso.. but experienced users needs lot of customizations to obtain many more features.. I hope that developers understand this..
