CipherFox will display the currently used SSL/TLS cipher and keysize in the Firefox status bar.
An extra, optional feature of CipherFox is that you can disable RC4 encryption in the options panel. RC4 encryption will then be disabled for all sites, and the next available cipher will be used, AES (eg. Gmail) or Triple-DES (eg. Newegg) in most cases.
By enabling that option, an "Enable RC4" option is added to the Tools menu to quickly toggle the cipher when it is needed.
You can check out what SSL/TLS you are using after you install this extension.
The CipherFox addon is cross-platform and it works on Mac OS X, Windows and Linux.
