I am using an extension called Black YouTube Theme (https://addons.mozilla.org/en-US/firefox/addon/black-youtube-theme/). Currently Whenever I start Firefox using restore session from last time. For any YouTube links I have open it pops open a little JavaScript Application box, one per link, which returns "Error: document.domain is null". That is the only problem I have, so I was wondering does anyone know how to disable JavaScript error messages using about:config?

capability.policy prefs aren't supported in current Firefox releases, so you can undo these steps.

If it only happens when you reopen pages automatically on the next start then this is likely caused by Firefox loading pages from the cache.

Maybe disable the disk cache or clearing the cache on exit (Clear history when Firefox closes) will prevent this alert.

So from my understanding I just put:

"capability.policy.default.Window.alert", "noAccess" "capability.policy.default.Window.confirm", "noAccess" "capability.policy.default.Window.prompt", "noAccess"

As new variables in about:config?

These didn't work. I still receive 1 JavaScript Application "Error: document.domain is null" for every YouTube page open on restart.

I have disk cache set to 0 and the Boolean variable set to false. So I do not believe it is a cache issue.

When was capability.policy removed? What next is going to be gutted out? I am really happy I use SeaMonkey.

It most likely has been replaced with a different name. I do not believe that they would remove something like that. Options/customization, is the whole reason I use Firefox. Without I might as well use Chrome.
