Essential security add-on which gives you control over the connections that websites try to make.
I am using the version 1.x beta which you can only get from the dev's webpage. this version is way easier to use than the regular version that you find here.
I hope the dev continues to develop this essential add-on.
As for possible improvements:
the chrome add-on http-switchboard has an interesting gui, it shows you what and where sth is requested (e.g. iframe), would be nice to have similar info in rp.
another improv. that I'd like to see would be the possibility to use wildcards anywhere in a rule/policy (in the current 1.x version it's only possible to use wildcards at the end of a domain name(e.g. example.com*).
