Rated 4 out of 5 stars

Latest Firefox 25 nightly builds show the full TLS ciphersuite name (like TLS_ECDHE_RSA_WITH_RC4_128_SHA) in the Page Info window; however, this might be an unintended change — it is not mentioned in the commit changelog, so it might still be reverted if someone decides that it breaks too much other code:

However, the CipherFox addon does not work in those nightly builds at all — the configuration dialog can be displayed, but the actual button with popup does not appear in the site information or addon bar.

This review is for a previous version of the add-on (3.6.3.1-signed).
