!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!warning: youtube enhancer plus does not support the material design version of youtube, and since mozilla has planned to disable xul addons like this one when firefox 57 will be released (source) i have decided to stop its development, so i highly recommend you to use enhancer for youtube™ instead.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
youtube enhancer plus will greatly improve your youtube experience! it allows you to disable autoplay for videos loaded in background tabs, remove ads from videos (automatically or ondemand), remove annotations, automatically play videos in hd or any other preferred format, play videos in cinema mode for a comfortable and distractionfree watching, resize the video player, automatically repeat videos, change youtube's style using custom themes, save your favorite videos and playlists to watch them in the builtin firefox sidebar while doing something else such as surfing the web, and more...
