Delete bookmarks.

I use xMarks - for my backup / sync of bookmarks (many thousands of them).

When I use a public internet computer - such as in a library or at college - when I am done - I like to make sure that my presence is cleaned up after me.

Before walking away - I'd like to erase my bookmarks - as well as the history, cache, form data etc etc.

Most of the programs I have seen so far - don't support a no-fuss way to erase the user bookmarks. (Naturally such an option wouldn't be selected/active for users on their own PC who would really like to leave their bookmarks in place).
