Can you please also clarify if the shortcuts used for copying and pasting are not working in the Web Console. By default they are on, and I do not believe there is a way to turn them off.

Do you mean registering an e-mail handler by setting the gecko.handlerService.allowRegisterFromDifferentHost pref to true on the about:config page and pasting a navigator.registerProtocolHandler() code in the command line (>) in the Web Console?

If you have finished all those steps and reset the gecko.handlerService.allowRegisterFromDifferentHost pref to false then you can close the Web Console via the close X or via "Tools > Web Developer > Developer Toolbar".

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

i used allow pasting, would like to turn that off so i cannot paste

I don't think that it is possible to grant pasting permission in current releases unless you mean the dom.event.clipboardevents.enabled pref on the about:config page.
