# Supported Web Browsers

For best performance, Affirm should be used on compatible web browsers. This guide explains which web browsers and browser versions are supported by Affirm.

We generally support the latest stable version release in addition to at least *two* previous major version releases for the following modern browsers:

| Type           | Combined % Desktop & Mobile |
| :------------- | :-------------------------- |
| Chrome         | \~ 66%                      |
| Safari         | \~ 13%                      |
| Firefox        | \~ 2%                       |
