I've started experimenting with an HTTPS Everywhere (
https://www.eff.org/https-everywhere) ruleset for arcgames.com
Saving the following as arcgames.xml in the /HTTPSEverywhereUserRules subdirectory of your firefox directory lets you import the ruleset.
<ruleset name="arcgames">
<target host="*.arcgames.com" />
<rule from="^
http://([^/:
@]*)\.arcgames\.com/" to="
https://$1.arcgames.com/"/>
<securecookie host=".*\.arcgames\.com$" name=".*" />
</ruleset>
So far the only glitch that I have noticed is that the embedded Youtube videos don't work. (Compare:
http://www.arcgames.com/en/games/neverwinter/news to
https://www.arcgames.com/en/games/neverwinter/news) However, that happens when using the secure site regardless of HTTPS Everywhere.
Your mileage may vary.
