I finished this within a few minutes. People keep using the word encrypted throughout this thread. The JavaScript isn't encrypted, it is simply encoded. Knowledge of how to use JavaScript classes is needed as well as knowledge about the DOM too.

Hope this helps without giving anything away.

I'm stumped. I tried to use a JS function to give me the value but I get the same document write w/e stuff, and I've tried using the DOM tab in firebug but I can't get that to work either.

Try looking into existing JS functions that convert characters expressed in specific formats (e.g. 2-digit hexadecimal numbers like \x32) to other formats. Also look at the format each set of hex numbers in the obfuscated set is in. The last set is in a different format to the rest. You may need to do some format switching on the sets of hex numbers so that the JS conversion function that you think may work can parse it. This can be done by copying and pasting the set of numbers into a text editor, then search and replace on the appropriate characters within the pasted string to get the desired format for whatever conversion function you think will work.

The solution to the level is right in the source code ; if you use the best-known Firefox add-on you'll get it in a second ;)
It is only after you have lost everything when you are free to do anything.

Yeah, I just did this mission, and it took me just under 20 seconds, not one piece of knowledge of DOM or encryption was required :D
I hope that's not a spoiler...

Look at the code, then use this http://home2.paulschou.net/tools/xlate/ once you isolate what you need!

I hope this is not a spoiler.

Actually, there's no need to use any other tools aside from Firefox's default made function. There's no need to use DOM inspector either.

I did it in less than a minute. Aside from that, I actually used this as my wordpress plugin long long ago until I removed it.

Firebug is the best tool to use for this mission in my opinion...
