If you want to know what encryption is being used with a specific site, right click and select "page info", or double-click the security icon that appears in the lower-left hand corner.
And, yes. IE supports only up to 128 bit (RC4, I believe). Firefox supports that as well as up to 256-AES (Advanced Encryption Standard - as defined by the United States Government)
