Downloads Blocked By Security Zone Policy

If you installed Firefox 3 and are using Windows, you might run into a problem where Firefox does not allow you to download exe files from the Internet due to a Windows setting. You will get the message: This download has been blocked by your Security Zone Policy and your download file will never download. To fix this problem you must modify Internet Explorer settings!

IE7 Security Settings
  1. Open Internet Explorer.
  2. Choose Tools menu – Internet Options.
  3. Click the Security tab and click on the Internet icon.
  4. Click the Default Level button if it is clickable
  5. Then click Custom Level… and navigate to Miscellaneous.
  6. Under this section find the option: Launching applications and unsafe files.
  7. Change it from Disable to Prompt (Recommended).
  8. Click OK, Apply, then OK.
  9. Startup Firefox again and test it to see if it works now.

IE 8 Browsers

If you are using IE 8, you should probably look at modifying these settings as well:

  1. Click on Tools – Internet Options.
  2. Click on the Security tab.
  3. Click on the Sites button and verify that the website URL is in the list of trusted sites.
  4. Back on the Security tab, click Custom Level…
  5. Locate the Automatic prompting for file downloads sub-category immediately under the Downloads category. Set the radial button to Enable.
  6. Locate the File download sub-category immediately under the Downloads category and set the radial button to Enable.
  7. Click OK to save the changes and Yes when prompted to confirm the changes.
  8. Exit completely out of all IE windows and then try it again

    This doesn’t work because when I click TOOLS, and click OPTIONS, the security system is completely different.

    Today, November 19, 2008, I was trying to download picasa.google.com and got the This download has been blocked …message. But I could download from other sites. What it turned out to be is that somehow–undoubtedly one of my security programs–had added *.google.com to the Internet Properties>Security>Restricted sites list. I removed it and was able to download.

    Bypass Windows Security Policy check

    You can add the new preference, browser.download.manager.skipWinSecurityPolicyChecks (available in current Firefox versions) and set it to true. This will bypass the Windows Security Policy check and allow you to download executable files. To add this new preference:

    1. In the Location bar, type about:config, and press EnterReturn.
    * The about:config “This might void your warranty!” warning page may appear. Click I’ll be careful, I promise!, to continue to the about:config page.
    2. Right-click anywhere in the list of preferences.
    3. In the context menu, select New then select Boolean. The “New boolean value” dialog box will appear.
    4. Enter the preference name browser.download.manager.skipWinSecurityPolicyChecksin the text field and click OK.
    5. In the “Enter boolean value” box that appears, select true and click OK.

    Firefox should now be able to download executable files.
