I jumped at the beta when it came out, shortly realizing a big bug. When I ever go on a flash or Java orientated page, eg: Youtube, Google Video, Gaming websites or most other pages it says this:
Bad Request

I luckily had Firefox installed and have to use it until the non-beta version is released.
