Ancient Maxthon 1.x or 2.x used to have this very useful extention to easily browse image galleries where it incremented the number at the end of the URL e.g. http://www.example.com/gallery/0123/001.jpg > http://www.example.com/gallery/0123/002.jpg > etc.. by just clicking on the [+] button. There was a Decrement [-] equivalent too.
While Chrome has such extension called URL Incrementer https://chrome.google.com/webstore/detail/url-incrementer/hjgllnccfndbjbedlecgdedlikohgbko?hl=en where you have many options and it works great, Maxthon doesn't seem to have it any more which is pity.
