[CentOS] NoScript allow scripts globally reversible?

I'm running NoScript because otherwise Firefox freezes up a lot.
Recently I've had difficulty accessing a site.
I suspect the reason is that it uses redirection in a way that
frustrates my efforts to give it permission.
To test the notion, I'm considering temporarily allowing script globally.
How hard is it to reverse?
Will I need to redo previous permissions one at a time?
