Such a preemptive approach prevents exploitation of security vulnerabilities (known and even unknown!) with no loss of functionality…
Experts do agree: Firefox is really safer with NoScript
NoScript works with Firefox 1.5 to 3.*. NoScript can be installed from the following firefox addon website:
Browse the URL from Firefox and click Install Now button. Once installed click "Restart Firefox" button for the addon to become active.
NoScript maintains a whitelist and it is important that you add your trusted sites in the white list to ensure proper functioning of the website. To do this, add the NoScripts Toolbar from View – Toolbars – Customize, select NoScripts icon and drag it to the Navigation toolbar.
Now, click on the NoScripts button and click Options, select Whitelist.
Add the website address of all your trusted websites. It allows you to Import and Export list as well.
Obvious, there is always going to be some website you don't remember. When you browse a trusted website (not added to the whitelist), a toolbar pops at the bottom of the website with an options button. Click the button and allow the website. Or if the site is not what you thought it was, then mark it as untrusted.
For example, try browsing a website like www.google.co.uk, you can see it blocking the scripts running from the website. A toolbar appears in the bottom of the page with an options button. Click the button and allow the domain, if you think google is a trusted site 😉
Now, that to me is your browser, your internet, your security while browsing in your control.
A great work by Giorgio Maone.
