There are quite a few options to protect select bookmarks from being accessible by other computer users. It is for instance possible to use a bookmarking service, use deeply nested bookmark folders or a start page service to list the bookmarks that other users should not see.
The options have in common that they hide the links but do not protect them once the page they are hidden on has been found.
Please note that this is an issue if you share the same user account on a computer, or if you let others access your computer at times. It is less of a deal if you are the only user of the account, as no one else can then access your local bookmarks.
Link Password offers an interesting alternative. The experimental Firefox add-on can encrypt links in the web browser so that their original destination cannot be revealed or guessed by looking at the bookmark.
The Firefox add-on will encrypt links with the AES encryption algorithm which means that users have to enter a password for that link to encrypt and decrypt it. It is currently only possible to encrypt one link at a time by selecting the "Make new Encrypt Link" from the Firefox Tool's menu.
Encrypted links use the newly defined cryptlink:// protocol. The add-on will automatically ask for a password when the cryptlink link is opened in the web browser. These protected links can be bookmarked.
An option to convert existing bookmarks into protected bookmarks would be nice but is not available at the time of writing. As would be the ability to protect multiple bookmarks with one password to use all of them normally once the password to decrypt them has been supplied by the Firefox user.
Link Password offers an interesting option for users who want to protect bookmarks in the Firefox web browser. It can be downloaded from the Mozilla add-on repository.
