Starting from today, you can add our Skype button on websites that use secure connection. The problem was that until this day, our server did not support HTTPS, which meant that on “protected” pages most browsers blocked active mixed content, the script not get loaded, and therefore button was not displayed. Now when our server is configured properly and supports HTTPS, you can add our Skype button on all web pages.

ps. If you notice any errors, please report them.
