Get the Coil Extension

The Coil Extension tells us when and where to stream payments. For the majority of web monetized sites, you'll need to install the extension for payments to occur.

We've partnered with some services that allow you to sign in with your Coil account (like Cinnamon) or link your Coil account (like Imgur). When signed in or linked with Coil, you don't need the extension to access their web monetized content. However, you'll need the extension to access all web monetized content outside of these services.

Supported browsers

Our extension is available for the following browsers. If you use private windows, you might have to give the extension explicit permission to access your online activities while browsing.

How it works

As you browse, the extension checks whether each page is web monetized by looking for a snippet of code called a Web Monetization meta tag. This snippet must contain a valid payment pointer.

When a page is web monetized, the extension shares an ephemeral (short-lived) identifier with the site, which the site uses to verify that your browsing session is monetized (i.e, that you're a Coil Member). The identifier is random on every page load. Then, the extension uses the payment pointer to request a temporary, encrypted payment address. The extension sends the payment address to Coil's servers, then we stream micropayments over Interledger to the address.

As long as you're active on the page, the extension will continue streaming payments. The extension stops paying if you leave the page, background the page, or are inactive on the page for long enough.

You can tell whether a page is web monetized, and whether the extension is paying, by checking the extension's status.

Browser permissions

What we ask for

When you install the Coil Extension, you’re asked to grant the extension certain permissions for it to work. The permissions it requests depends on your browser, and can sound excessive or even scary. For example:

  • The Chrome, Brave, and Edge extensions want permission to read and change all your data on the websites you visit.
  • The Firefox extension wants permission to access your data for all websites and access browser activity during navigation.

If you dig deeper into Firefox’s “access your data” permission, you’ll see statements like, “Extensions requesting this permission might...read and write details of your username and password.” These descriptions are written by each browser provider and are meant to cover a variety of scenarios.

Why we ask for it

In short, we ask for these permissions because browser providers don't offer a better choice.

Since browser providers don’t offer a permission that’s specific to how our extension works, we have to use pieces of what's already available. This means we have to use permissions that ask for more than we need and use. That’s the big reason why our extension is open source. You can check the source code to see what it’s doing: https://github.com/coilhq/web-monetization-projects/tree/master/packages/coil-extension. Our extension does not access, record, or transmit any personally identifiable information (like your name, username, or password) nor does it track your browsing history.

For more information about how we respect the privacy of our users, you can check out our CTO’s blog post, Doubling Down on Privacy, and review our Privacy Policy.

Troubleshooting

My Coil extension isn't working.

Content on coil.com isn't unlocking and/or videos on Cinnamon fail to play.

If you're only experiencing issues on Coil, sign out and back in to your account. This solves the problem most of the time.

If you're experiencing issues on both Coil and Cinnamon:

  1. Sign out and back in to Cinnamon using your Coil account. Try again.
  2. Install the Coil Extension and try again.
  3. Open a private tab in your browser, then sign in to Cinnamon with your Coil account.

If you're still having problems after trying these steps, contact our support team.
