Topic: Is it in any way possible to deactivate all scripting?

Is it in any way possible to deactivate all scripting? Maybe through Umbrella? Maybe through another extension?
It would be cool to have that that all is deactivated by default and only turned on demand.
That really would close (almost) all security and privacy leaks.

There a few extensions out there which (at least try) do this.
Like e.g. NoScript (most common, but there are better out there ... and unfortunately more complicated to use) ... and similar.

Maybe you can fetch some ideas from them and or work together.

Re: Is it in any way possible to deactivate all scripting?

Yes.  In the Settings page, Under Privacy, click on Content Settings, then set Javascript to "never allow".  You can put white-listed websites in the exceptions. 

We should add NoScript or a similar extension to the allowed extensions for Epic.  We have not integrated such functionality into Epic because almost so many websites depend on Javascript so it's impractical/difficult to use.

Good thought about integrating turn off/on javascript in the umbrella button.  That would be nice, but we feel it would see very little usage so it's a low priority at this point.
