Can I disable SOP (Same Origin Policy) on any browser for development?

Question

I want to develop JavaScript on my Windows machine. Do you know a browser where I can turn off Same Origin Policy so I can develop locally? Firefox would be optimal

Answer 1

In Chrome (& Chromium) 48 and above you should add the flag --user-data-dir like this:

chromium-browser --disable-web-security --user-data-dir

And it works.
