Hello, i am a web developer in a company.

From this week on, all the colleagues around me and the web customers cannot open the embedded pdf data any more.

The way we transfer data protocol, data:application/pdf  example can be found in plunker http://embed.plnkr.co/Bjkypkht4RjIWE1AyFP0/index.html

Shortly, we put data in data:application/pdf and use window.open() method to open the pdf binary data in browsers.

This function works normally before this week, it in fact works for almost one year already in both IE/Firefox/Chrome browsers with pdf add-on or viewer plugins.

But this week on,  all IE versions does not work any more, error shows as following, can anyone help me to find out the reason?

Error as follows:

I guess this is the problem of IE or Adobe, but since Adobe is not updated before, IE is set to update automatically, so i first come here for help, thanks.

Please do not tell me to reset IE or enable/disable IE, all these methods have been tried by us but didn't work.
