Also, is this the correct list of all the islands I would need for an all islands speedrun?

Early Poptropica, Shark Tooth, Time Tangled, 24 Carrot, Super Power, Spy, Nabooti, Big Nate, Astro-Knights, Counterfeit, Reality TV, Mythology, Skullduggery, Steamworks, Great Pumpkin, Cryptids, Wild West, Wimpy Wonderland, Red Dragon, Shrink Ray, Mystery Train, Game Show, Ghost Story, S.O.S, Vampire's Curse, Twisted Thicket, Poptropolis Games, Wimpy Boardwalk, Lunar Colony, Super Villain, Charlie and the Chocolate Factory, Zomberry, Night Watch, Back Lot, Virus Hunter, Mocktropica, Monster Carnival, Survival 1-5, Mission Atlantis 1-3, PoptropiCon 1-3, Arabian Nights 1-3, Galactic Hot Dogs, Mystery of the Map, Timmy Failure, Escape from Pelican Rock, RealityTV: Wild Safari, Fairy Tale, Goofball, Legendary Swords

I'm somewhat planning on speedrunning Poptropica at some point and was wondering some things.

• Can I use Flashpoint for speedrunning AS2 islands?
• Can I use an old version of Chrome to speedrun AS3 islands?
• Would I be allowed to switch between Flashpoint, Pop on old Chrome, and Pop on new Chrome in order to do runs with multiple islands?
• I'm kinda new to speedrunning, so how do I set up a timer in a recording/stream? Thanks
