BTW, with stable ABP I see 2 error messages: Refused to create a worker from 'blob:' because it violates the following Content Security Policy directive: "child-src http: https:".

_0x7203x16.(anonymous function) @ Uncaught DOMException: Failed to construct 'SharedWorker': Access to the script at 'blob:' is denied by the document's Content Security Policy.
    at HTMLScriptElement._0x7203x16.(anonymous function) (

They doesn't appear with dev version. WS connection doesn't appear either, though. Probably due to being initiated from a SharedWorked which doesn't belong to any specific page.

I can't reproduce this as described with Chrome Version 56.0.2924.87 (64-bit) and Adblock Plus built from current master. Are there any steps to reproduce that I'm missing?

(Sounds like it might have been either caused by the change in #4770, or a duplicate of #4807 which is still waiting review.)
