I need at least 128 bit encryption to access secure sites. What level of encryption does Firefox have and how do I check it?

Many banking sites require you to confirm that you have at least 128 bit encryption on your browser. I allowed a site to check the encryption on my browser (Firefox/Windows) and was told I didn't have at least 128 bit encryption. I'm not the most computer savvy, so I don't know how to check or increase encryption, so if someone could guide me, I'd really appreciate it.

Right-click on the web page and select View Page Info. The Security tab will show the level of encryption being used in "Technical Details" at the bottom of that tab.

Firefox matches the level of encryption used by any secure website, and will easily do more that 128-bit encryption.
