Trusted website list

Browser security depends on establishing the identity of individuals and organizations who wish to transact business over the internet, and providing them with a secure channel in which to do so. You can manage the security environment provided by Opera through the security preferences.

Opera uses a set of whitelists to help protect you from insecure extensions and fraudulent or malicious websites. If you attempt to download an extension from a site that is not on the whitelist, you will get a warning: "For your safety, you can only install extensions from addons.opera.com." If you nevertheless want to install the extension, you have two choices:

• Find an equivalent extension on addons.opera.com
• Add the extension's web address to the whitelist

If you believe that extension comes from a trustworthy source, take the following steps to add the source to the whitelist:

1. From the menu, go to Settings > Preferences > Advanced > Security.
2. Click the "Trusted Websites" button.
3. Choose the relevant tab: Trusted Repositories or Secure Internal Hosts
4. Click "Add" and enter the web address of the site. You can also edit or delete sites in the list.
