Sleazy Fork is available in English.
Can work on almost any webcomic/manga page, preloads 5 or more pages ahead (or behind), navigates via ajax for instant-page-change, lets you use the keyboard, remembers your progress, and it's relatively easy to add new sites
Yes, Batoto changed their domain. Just adding the new domain doesn't seem to work.
You also need to change the block (or duplicate) the block that has url: 'batoto.net', and change it to url: 'bato.to'
Done
Site changes
