I've used the chrome extension "Mt Gox Peek" for a few months now and it works great. All it does is show the current price of bitcoins in the top of the browser. However, today it's asking for permission to update the terms. The exact quote is:
"The newest version of Mt. Gox Peek has been disabled because it requires more permissions. It can now - Access your data on mtgox.com and
www.forex.com".
That seems bad to me. It's just supposed to display the price, why would it need to access my mtgox data? And what the hell does forex have to do with anything?
