Trust Wallet does indeed have a browser extension, similar to MetaMask. However, unlike MetaMask, you do not need to connect the browser Trust Wallet to your wallet via Wallet Connect. This means that you can use the mobile version of Trust Wallet to store and manage your cryptocurrencies, without needing to use a browser extension. Furthermore, Trust Wallet offers a range of features that make it an attractive choice for users, such as support for multiple blockchains, a built-in exchange, and a secure, private key-based system. Therefore, if you are looking for a secure and convenient way to manage your cryptocurrencies, Trust Wallet is worth considering.
