Supported Browsers

Horizon is primarily tested and supported on the latest version of Firefox, the latest version of Chrome, and IE9+. Issues related to Safari and Opera will also be considered.

This page aims to informally document what that means for different releases, everyone is warmly encouraged to update this page based on the versions they’ve tested with.
