When trying to log on to a certain site, it says "The Browser cipher strength has to be set to 128-bit." What does this mean, and how do I fix it?

The details are in the question I just asked. In case you have difficulty reading, here it is again:

When trying to log on to a certain site it says:

It won't let me log on until I comply with this.

And thanks for the lesson in redundancy!

The website is likely still incorrectly browser sniffing for the U that used to be in the Firefox useragent before Firefox 4.0 when it is common knowledge that Firefox easily supports 256-bit (since beginning) if site provides such support. For example https://www.fortify.net/sslcheck.html

Have you contacted support on this?

If websites complain about 128 bit encryption not available then that can be caused by the "U;" that is no longer present in the Firefox user agent. Firefox actually supports 256 bit encryption ciphers

@Dbellca82, the Firefox 2.0 release was released in October 2006 not 2002. Also the browser supported 256-bit long before Firefox 2.0 anyways since it was called Phoenix back in 2002/2003.

The US government lifted export restrictions on browsers made in the US with regards to encryption strength in 1996, so that website must be using an ancient "sniffing" script.

Further changes came in 2000 with US Dept of Commerce regulations for computer software, specifically.
