When you’re using NoScript for Firefox and you want to allow scripts from a certain Website, all you have to do is look up in the address bar and read the name of the Website that you’re currently on, then go down to the bottom of the page where the NoScript plugin icon is and click once to bring up the menu and once more to allow or forbid scripts from that particular Website.
Using CookieSafe is just like using NoScript but instead of blocking active content on a Webpage, you’re blocking cookies from Web pages. When you block cookies from a website (like Youtube), you won’t be able to log in to upload your videos. Cookies are a way of letting websites know that it is in fact you that’s trying to log in. There is an easy way around this however, as there is in NoScript. Just click the menu item at the bottom of your web browser to allow cookies from the site you’re trying to log into.
