How do I install the Single Player Commands mod on Minecraft for free?

I play Minecraft for free, which is basically Minecraft but it's cracked. I didn't download the game because it plays in my internet browser. I play the latest version which is 1.0.0, I'm trying to install Single Player Commands but it doesn't work! I need help! It would be great if I had a step by step guide on how to install it, thanks.

Well. i tried. I use a cracked Minecraft too but it dosnt affect gameplay at all. when i updated to 1.0.0, i reinstalled a NEW version of Too Many Items and REI's Minimap. Both Mods were 1.0.0

However, when i tried to instal SPC, It gave me a 1.8.1 version. You need a 1.0.0 Version of SPC. IT hasnt come out yet

 Ansver:

minecraft single player commands for minecraft 1.0.0 isn't out yet sadly but please tell me when it is.
Plus i recommend www.minecraftdl.com because i found it is quick and easy to use and it generally gives you what you want. thanks! :)

 Ansver:

you cant install mods if you are using the browser version. just buy the game. secondly, there is no singleplayer commands for 1.0.0 yet.
