Yeah, my NoScript whitelist contains 1196 lines.  Still, the sites I
visit and trust simply work.  A new site that depends on javascript
either gets closed, given temporary permission, or whitelisted.  It's
not so very different from the decision to load email images, except
Evolution has no whitelist.  I decide on a case-by-case basis.

The security works.  Is it worth the grief?  I've decided yes, but I may
be excessively paranoid.
