# Supported Browsers

In order to have the best user experience with Zscaler MDR, we recommend using Google Chrome. Chrome is the most widely-used browser with the best security and adherence to accepted internet standards.

We officially support the following browsers:

- Chrome — We officially support and test with Chrome and support the last two versions.
- Firefox, Edge, and Safari — The latest versions of Firefox, Edge, and Safari should work, but may yield unpredictable results.

If you use Zscaler MDR on an older or unsupported browser, some features may not work:

- Some sections may look different
- 2FA may not work properly
- Some functionality may be lost (Automate, authentication, etc.)

## Required Settings

Zscaler MDR requires the use of [two-factor authentication](/doc/docs/configure-multi-factor-authentication-mfa) (2FA) for all user logins. Please note that issues with 2FA are commonly associated with ad-blocking extensions. Some combinations of browsers and ad-blocking extensions can cause certain HTTP POST requests to fail. If you experiences 2FA problems, disable ad-blocking extensions for your Zscaler MDR subdomain(s).

## Using an Unsupported Browser

If you use Zscaler MDR on an older or unsupported browser, some features may not work.

- Some sections may look different
- 2FA may not work properly
- Some functionality may be lost (Automate, authentication, etc.)
