IE 10 and 11 don't allow construction of Web Workers from blob urls. A SecurityError is thrown when the blob url is passed into the worker constructor. The specifications for Web Workers allow this behavior if a browser policy (like the same origin policy) is violated, but (according to the origin policy laid out in http://msdn.microsoft.com/en-us/library/windows/apps/hh453196.aspx) this should not be the case here.

All other browsers that support the necessary APIs for workers, blobs and object urls (every browser but the android browser and IE < 10) don't have this problem.

Thank you for the feedback. This issue appears to have been fixed in Microsoft Edge. We're not presently working on feature bugs in Internet Explorer outside of security-related issues.
Best Regards,
The Microsoft Edge Team
