got followings in devtools console:

Blocked script execution in 'about:blank' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.
Blocked script execution in '' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.

is there any way to avoid this? thanks!
