Facebook authorization with https results in 404 error or in an untrusted connection
Answer
Since April 2012 we are using a real certificate and this problem does no longer exist!
When Facebook authorization is done via https a security certificate is needed. We at 1st-movers.com has no real certificate at the moment (because this is expensive).
But this is not a real problem: You can trust the connection and the connection is secure!
Firefox and most other browsers
If the dialog does appear please click on "I Understand the Risks" and push the button "Add Exception". In the following dialog please confirm the security exception as described in the dialog.

Internet Explorer 9
In IE9 the dialog looks different. Please allow the browser to display the content and push the button on bottom right.

Google Chrome
There is an issue when you try to authorize the app via the AutoTweet backend channel dialog button/link under Google Chrome: "Error 501 ERR_INSECURE_RESPONSE" or something else.
This error is comming up in newer versions of Google Chrome only and only when you do the authorization. So please use a different browser when doing the authorization for Facebook.
EDIT: I've found out that this is a known problem with Google Chrome and SSL certs in iFrames. See here: http://code.google.com/p/chromium/issues/detail?id=87957
And here is a workaround:
1. Copy the displayed (iframe) link.
2. Open the link in a new tab and click 'Proceed anyway'.
