Alright, as we seem to be shouting back and forth about the security thing, I figured I might as well clarify a few things, as also I have done quite a bit of research into this.
Basically what this script does is remove the internal messenger checks to check for virus-urls and things like that. These checks are mostly done on the server side too, but I am 100% certain that the messenger team has a very good reason to also do this on the client side. If you ask me, bluntly removing security checks is something you should not do. And to be quite honest, simply naming it "anti-freeze" without even informing users what exactly is removed, isn't something I appreciate.
I've written my own method to speed up the security checks (by replacing certain ones with faster, yet equivalent, checks), which (as vikke said) will be in P3, but to clear things up I've also taken a quick look at this script, and I've noticed that it doesn't even do properly what it is supposed to do. It removes all but one security check, but in the mean time allows for another freezing/crashing method: It will crash if there is only one security check received from the server...

So actually, using this script you do, in fact, risk something. It does remove the freezing upon huge messages, but it also removes some (in my eyes) vital security checks, and creates some new problems that won't do any good to messengers overall stability...
Use this at your own risk.
