This add on was pretty useful until a few days ago when it stopped working. A few days ago there were some changes on nhentai(dot)net and after that it stopped working.
Hey, thanks for letting me know it doesn't work. I've just pushed an update to fix it and make it much faster. It should be available once Firefox approves it.
EDIT: I'm aware of an issue where loading images isn't reliable. Will take a look at it, whoops!
