Puma Browser: Support Creators and Developers - Apps on Google Play
Puma Browser is a fast and privacy focused mobile web browser with access to new premium content network and a new way to support creators directly. The ad-driven business model turned the web into a vicious, snooping, clickbait-driven distraction machine. We'd like to deliver better incentives for high-quality content creators and offer users a premium, private, and distraction-free browsing experience. Better search options to choose from: • (default) DuckDuckGo – Privacy, simplified. DuckDuckGo is an internet search engine that emphasizes protecting searchers' privacy and avoiding the filter bubble of personalized search results. • Ecosia – plant trees while you search the web! On average you need around 45 searches to plant a tree so search on! • Wikipedia – free online encyclopedia, created and edited by volunteers around the world and hosted by the Wikimedia Foundation. • Twitter – arguably the most useful social network according to our CEO :shrug: • Good ol' Googz if you like it. Thanks to partnership with you can now support the publications and creators directly when they are using Web Monetization. What you get as a member? • Access to all web monetized content everywhere on the internet with strong privacy protection. • Access all exclusive content on Coil Explore. • No tracking. Your privacy is our top priority. • Access the entire video library on • Play games on in distraction free mode. • Support Twitch streamers while you watch their streams. • Support creators that have Web Monetization enabled content.

How it works

The extension checks if a page is web monetized by looking for the Web Monetization <meta> tag. If the page has the meta tag, the extension tells Coil to start paying over Interledger to the payment address in the tag.

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

Browser permissions

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 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.

When a content creator sets up a wallet through a third-party service, the service provides the creator with a payment pointer. The creator incorporates a Web Monetization HTML tag into their website using the payment pointer. This is what it means for a page to be web monetized.

The extension must read each page you visit and look for the Web Monetization HTML tag to determine whether the page is web monetized. When you visit a web monetized page, the extension is provided with the creator’s payment pointer. The extension then resolves the payment pointer to an ILP address. The address is sent to Coil’s servers and allows us to pay the creator.

The extension shares an ephemeral (short-lived) identifier with the creator, which the creator uses to verify that your browsing session is monetized. The identifier is random on every page load. Our extension does not access, record, or transmit any personally identifiable information nor does it track your browsing history.

Since our supported browser providers don’t offer a permission that’s specific to how our extension works, we have to use permissions that ask for more than we need. That’s the big reason why our extension is open source. You can check the source code to see what it’s doing:
