Turn all links on a page into https within firefox

Lets just say that I wanted to be extra careful with the website I'm visiting (irrespective of whether the site is offered in https) and wanted to convert every hr开发者_开发知识库ef in the web page received into its https equivalent.

Is there a way/add-on to do this ? or do I have to write my own :(

As Paul said, most sites will break if you do this. However, if you wanted to do something similar to this (grabbing all the links on a page and doing something to them), a Greasemonkey script would be easier and quicker than writing a Firefox add-on.

You can't just point all links to https, most of them will break, and secure sites will redirect you to https anyway.
