Excellent add on! What this add on does is fix the broken infinite scroll on Instagram caused by the scroll style android style scroll bars add on. Scroll style 1.2.1 is the only web ext add on which works well for Youtube videos that makes the scroll bar minimalistic as well as fade in and fade out! This is the only add on that fixes Instagram images from not loading while using scroll style 1.2.1. Scroll Style 1.2.1 together with scroll anywhere 5.6 and this add on is the way to go. GJ ,good looking and working add on!
