Link Password is a free Firefox extension that can secure bookmarks using a bit of javascript and AES based encryption. Once protected the original bookmark can’t be determined nor it’s ultimate destination deciphered – unless you provide the correct password. The extension registers it’s own protocol under the linkpassword:// banner so integration remains tight within Firefox – meaning you can continue to leverage the built-in bookmarks manager of Firefox even while some or all of it’s contents are encrypted.
Encryption or decryption can be initiated by right-clicking on the desired bookmark and choosing Encrypt link. You can also encrypt full bookmark folders with all their contents.
Further, encryption can also be applied through the address bar where a new icon appears on mouse-over.
The process is simple – just supply the password you wish to use and decide whether you wish to Rename the bookmark links or not. Renaming is strongly encouraged as generally, the name alone can reveal more than you wish and as such, quickly defeats the purpose of this extension. Links are renamed to random Wikipedia articles or Bing and Google searches. However, and quite ironically, in testing one of the obscured bookmarks was actually renamed to Wikipedia – Porn.
Subsequent visits to a now protected bookmark will result in a password dialog – supply the correct password and the bookmark loads in Firefox just as you’d expect.
Tight browser integration is really the key component of this extension. Testing was done within Firefox 4.0 but the extension is compatible with older releases if you’ve yet to take the 4.0 plunge.
