Le véritable avantage de cette extension sur d'autres proposant des fonctionnalités équivalentes (ForceTLS ou le trop bedonnant NoScript), c'est de ne pas se limiter à transformer http et https dans les urls concernées. L'exemple des sites liés à wikimedia est très informatif à ce sujet:
#cat Wikipedia.xml
<!-- www.wikisomething.org is generally a valid
domain containing general information on a project and is
simply not available at all in HTTPS. Everything with a /wiki
suffix, however, is a language-specific page that is available in
HTTPS. Hence these rules avoid redirecting www.wikisomething.org,
while redirecting all language-specific subdomains. If you
navigate first to the WWW page, you could be vulnerable to SSL
stripping, but if you succeed in submitting a query from there
in a specific language without interference, you'll subsequently
be protected. -->
