EFF has been working on one called HTTPS Everywhere:

https://www.eff.org/https-everywhere/

There are some subtle issues around situations where a site
supports HTTPS for some resources but not others.  For example,
you can currently use

https://www.google.com/

for encrypted web search, but only the unencrypted form

http://www.google.com/language_tools?hl=en

for translation services.  As a result, HTTPS Everywhere has a
database of rules with exceptions, so that a rule can apply to
only a portion of a site.

This may not do exactly what you want because you might prefer
to block HTTP URLs entirely, rather than allowing them only if
no HTTPS equivalent exists.  You could probably achieve this in
HTTPS Everywhere by adding a local wildcard rule that matches
every HTTP site and redirects it to an intentionally broken
page, such as a URL within your local host.  The means of setting
up your own local rewrite rules are described at
