What's the difference between the browser extension and the desktop applications?

TunnelBear for Chrome/Opera is a light-weight browser extension that secures your browser traffic and helps you browse privately, as if you're in another location. The browser extension only encrypts your traffic for that particular browser, unlike the TunnelBear computer and mobile apps which encrypts all traffic from the device (including apps and services outside of the web browser).​

For maximum privacy, we recommend using the TunnelBear application for Windows, Mac, Android, and iOS. However, if you spend all of your time in the browser, and ease-of-use is your priority, then the TunnelBear browser extension should more than meet your needs.
