https://github.com/flamingspaz/cloudflare-email-firefox-addon Cloudflare Email Routing Alias Generator A Firefox extension that generates a Cloudflare Email Routing alias for the site you're currently visiting and copies it to your clipboard in one click. Setup 1. Create a Cloudflare API token Go to dash.cloudflare.com/profile/api-tokens and create a token with these four permissions: | Scope | Permission | Level | |---|---|---| | Zone | Zone Settings | Read | | Zone | Zone | Read | | Zone | Email Routing Rules | Edit | | Account | Email Routing Addresses | Read | 2. Configure the extension Open the add-on's Options page (right-click the toolbar icon → Manage Extension → Preferences, or click "Open options" in the popup), paste your API token, and click Save. Usage

Navigate to any website you want to sign up on.
Click the extension icon in the toolbar.
The alias field is pre-filled with a random alias for the current site — edit it if you'd like a custom one.
Choose which verified address the alias should forward to.
Select the alias domain from the dropdown.
Click Generate & Copy.

The routing rule is created in Cloudflare, and the full alias is copied to your clipboard, ready to paste into the sign-up form. Use the Manage aliases → link in the popup to open the Cloudflare dashboard for the selected domain. Alias format Aliases follow the pattern {site}-{word}{digits}@{your-domain} — for example, visiting github.com might produce github-apple1234@example.com. The site name makes aliases easy to identify; the random suffix makes them unique. Requirements
