Security problems

Hey,

thanks for a great plugin.
i am considering buying it, but tmy browser keeps signaling it is not secured.
ever since i installed it, i get a “Mixed content is blocked: secure” on the ssl sign, and when i enter the plugin itself i get “A grey lock with an orange triangle indicates that Firefox is not blocking insecure passive content.”
what should i do? and how can i count on the pro version to be safe?
