So I've got Leopard and I browse with TenFourFox with Adblock Plus, Flashblock, and HTTPS Everywhere installed. I'm thinking about adding NoScript to the mix for greater security, as I do on Windows. I'm glad I have Flashblock since there's already plenty of vulnerabilities in the last versions of Flash for PPC which will forever remain unpatched. Do you think adding NoScript is worth it? I guess it can't hurt... any comments?
