thanks for this great tool!
I just noticed that my WHOIS popout of a IP entry is blank.
A quick look into Chrome Dev Tool Console (F12) revealed that mixed secured content is the issue.
We have to run our backends in SSL (HTTPS) and the call you do to infosniper has to be in HTTP (they do not support SSL).
I suggest to open the popout as a IFRAME. Hope that is accomplishable.
I also suggest that you base the IFRAME solution only for the HTRPS case, and keep the current implementation for open protocol.
If this is too hard to get straightends, you may just use a traditional popup window - no problem with that
