Security Notes

Install NoScript and enable ‘Forbid scripts globally’ to improve the security of your browser by preventing 0day JavaScript attacks. This is a drastic option as it will render many websites unusable as they rely heavily on JavaScript.

NoScript offers a whitelist you can use to selectively enable JavaScript for sites you trust, but this is considered especially bad for your anonymity if you're using NoScript with Tor Browser.
