Coinbase® Extension® - Getting Started:

Seamless crypto management: Coinbase Extension. Real-time data, secure trading, and easy portfolio control, all within your browser's reach.

As of my last knowledge update in January 2024, Coinbase primarily offered a mobile application called "Coinbase Wallet" for managing and storing cryptocurrencies. However, developments and updates may have occurred since then.

If there is a new Coinbase Wallet browser extension, it would likely be designed to provide users with convenient access to their cryptocurrency holdings and related features directly from their web browsers. This could include functionalities such as checking balances, sending and receiving cryptocurrencies, accessing decentralized applications (DApps), and possibly facilitating easy transfers between Coinbase accounts.

To get accurate and up-to-date information on any Coinbase browser extension, including details about its features, setup, and usage, I recommend checking the official Coinbase website or contacting Coinbase support. Additionally, you can explore your browser's extension store (e.g., Chrome Web Store, Firefox Add-ons) to see if there is an official Coinbase Wallet extension available for installation.

Please note that the information provided here is based on the state of knowledge up to January 2024, and developments in the cryptocurrency space may have occurred since then.
