By default, Firefox will initiate the download of an executable file specified in the http header. This occurs without active scripting, which means standard security addons such as NoScript will not prevent this from occurring. To prevent unintentional redirects or malicious downloads, follow the instructions below to disable http header refresh in Firefox v3 (feature not available in previous versions; upgrading and disabling is recommended).
Time Required: Less than 2 minutes
- Open the Firefox browser
- Click Tools | Options | Advanced
