Browser-protected pages

When using a web extension like AdGuard Browser Extension, there are certain restricted domains that prohibit access or permissions. As a result, ad blocking extensions are not allowed to interact with or modify the content of these pages. In other words, they are not allowed to block ads and other annoying elements on these web pages.

Chromium browser restrictions

Chromium-based browsers, such as Google Chrome, maintain a list of restricted domains that extensions are not allowed to access. These domains include:

  • clients.google.com
  • clients[0-9]+.google.com
  • sb-ssl.google.com
  • URLs starting with chrome://, chrome-extension://, or https://chrome.google.com/webstore/
  • PDF files
  • Pages where Javascript is disabled
  • Security warning pages
  • Error pages such as 404 errors and network errors
  • URLs starting with view-source: or data:

Firefox browser restrictions

Similarly, the Firefox browser has its own set of restricted domains where extensions are not permitted to operate. These restricted domains include:

  • accounts-static.cdn.mozilla.net
  • accounts.firefox.com
  • addons.cdn.mozilla.net --
  • addons.mozilla.org
  • api.accounts.firefox.com
  • content.cdn.mozilla.net
  • discovery.addons.mozilla.org
  • install.mozilla.org
  • oauth.accounts.firefox.com
  • profile.accounts.firefox.com

Modifying restrictions in Firefox

Changing advanced settings can affect the stability and security of Firefox. This is recommended for advanced users only. If you are aware of the associated risk and still wish to enable add-ons disallowed on a protected page, follow the steps below:

  1. Click the menu button → Add-ons and themesExtensions.
  2. Click the extension you want to enable on sites with restrictions (In this case, AdGuard).
  3. Select Allow in the section Run on sites with restrictions.

Alternatively, you can:

  1. Open a new tab and type about:config in the address bar.
  2. Press Return. You may encounter a warning. In this case, click Accept the Risk and Continue.
  3. Search for extensions.webextensions.restrictedDomains. If you can’t find this preference, you can create it. Simply select the Boolean type and click + to add it.
  4. Click the toggle button next to this preference and change its value to false.
  5. Restart Firefox.
