Q403: How do I enable the experimental Javascript feature?

A403

This is pretty simple. Just go to chrome://flags.

unsafeWindow_flags

Now a page with all experimental Chrome featues is shown - search for 'Javascript'.

unsafeWindow_experimental

Click 'Enable' and 'Relaunch now' at the bottom of the page.
