Personally I choose to disable this annoying popup, and simply have Internet Explorer display nonsecure items anyways.
Because everytime while playing facebook and when i attempt to send gifts or request items in Cityville, facebook gives you that annoying popup, however other games are fine like farmville, i don’t know why. (below)
Anyway here’s how to disable these Facebook popups and show nonsecure items anyways, simply follow these steps:
1.In Internet Explorer 9, go to the Tools menu > Internet options.
3.A Security Settings window will appear with numerous options, scroll down a little past half way down, you will see an option labeled Display mixed content, there you can choose Enable (which will always display nonsecured items without asking)
4.Click OK, and a dialog asking if you are sure you want to change the settings for this zone, be sure to click Yes.
5.Now click Apply and you are done.
