Greasemonkey, which can be downloaded at https://addons.mozilla.org/en-US/firefox/addon/748 , has many great scripts, and I'm going to post a directory of them here. Dailies Daily Doer by Fexxel http://userscripts.org/scripts/show/52005 Once this script is installed, you can go to a web address and your dailies will be done. Just remember that not all dailies are covered. Neopets - Dropdown Dailies Like it says in the name, this will add a dropdown menu with dailies. Autoplayers Carnival Games player by Mobscene http://userscripts.org/scripts/show/35634 Plays Bagatelle, Cork Gun Gallary, and Coconut Shy. Plays all your tries in a matter of seconds. Ultra fast. Additionally, it logs all of what happens. Amazing script. Double or Nothing Player by Mobscene http://userscripts.org/scripts/show/35703 Self Explanatory. Dice a Rite http://userscripts.org/scripts/show/2445 I love this script. It runs lightning fast, and stops on the Silver Die. Beware of the Pant Devil. This is excellent for getting the Dice a Roo avatar. Neoquest I Trainer http://userscripts.org/scripts/show/54819 This script will move left and right, leveling your NeoQuest characters. SnowWars Autoplayer http://userscripts.org/scripts/show/46013 Goes in rows clicking on squares until it's hit all the little guys you need to find in Snow Wars. You have to do the rest though, it's not fully automated. Cheeseroller Autoplayer http://userscripts.org/scripts/show/46016 Plays Cheeseroller for you. The game is chance so if you're lucky, good for you. Kiss the Morthog 'Kisser' http://userscripts.org/scripts/show/45799 Auto "Kisser" Auto Potato Counter http://userscripts.org/scripts/show/28364 Plays the original version of Potato Counter for you. It auto enters the amount of potatoes. Cheat Cheat http://userscripts.org/scripts/show/33483 This incredible script allows you to choose any number option during a game of cheat. Essentially an auto trophy. Tyranu Evavu Player http://userscripts.org/scripts/show/28580 Uses a good algorithm to determine what to pick. Lunar Temple Picker http://userscripts.org/scripts/show/28359 Picks the correct one. Scorchy Slots Player http://userscripts.org/scripts/show/46014 I like this a lot, but it's a little slow. Pyramids Player http://userscripts.org/scripts/show/34037 Uses a good algorithm Autobuyers-What you've been waiting for DZ GM ABer http://userscripts.org/scripts/show/58731 The dominant autobuyer. Lets you save different lists and refresh rates for each shop. Doesn't have wait times or stop for RS ban, though. Often slow buy times. Backslash Buyer http://userscripts.org/scripts/show/60969 Has RS Ban feature and wait feature, but one can't save a list for different shops. Greasemonkey Autobuyer http://userscripts.org/scripts/show/53263 The comments here say it isn't safe, but it is. Excellent features, no list saving, but probably much faster buys than the DZ buyer. Auto Haggler http://userscripts.org/scripts/show/53584 If you want to do the clicking, this is for you. No smart haggle though. These four are the best, there are also many buyers specific to one shop, which can also work well. Other Scripts Shop Wizard AddOns Quick Price Checker http://userscripts.org/scripts/show/61379 This allows you to highlight an item where ever you are, press alt and w, and it will become a link to the shop with the lowest priced item. I love it! Lowest Price http://userscripts.org/scripts/show/46010 This will add the lowest price found so far to the top of each search. Extremely useful. Set Shop Wizard to 'Identical' http://userscripts.org/scripts/show/30306 Self Explanetory Use the Shop Wizard during Faerie Quests http://userscripts.org/scripts/show/33958 Again, you already know what this does. Site's Looks Ad Remover http://userscripts.org/scripts/show/24823 Removes all ads from Neopets. Remove the Nickelodeon Bar http://userscripts.org/scripts/show/58716 I can't stand that thing. Random Neopets Board Bumper http://userscripts.org/scripts/show/34859 Be careful with this script. 1000 NP Score http://userscripts.org/scripts/show/42394 Shows what score you need to get 1000 Neopoints. That's all for now, thanks for looking.
I've read somewhere that you should be very careful about using the potato counter script, and that TNT is/was watching for it.
