In my own webapp, under Developer Tools window, I tried to run window.open('https://www.google.com','_blank'), but got the following error:
Blocked opening 'https://www.google.com/' in a new window because the request was made in a sandboxed frame whose 'allow-popups' permission is not set.
I can run this Javascript command in other website. Plus I tried the answer of this question: window.open popup blocking issue, but still no luck.
Is there a way to set 'allow-popups' permission ?
