Supported Devices and Browsers
CS First works best on desktop or laptop computers. CS First works best in the newest and last prior version of these browsers:
Without the most up-to-date version of your browser, you’ll still be able to use CS First, but you may have problems using newer features. Each time a new browser version is released, we begin supporting that version and stop supporting the third most recent version.

If you are presented with a blank screen or message stating there was a "connection error," you may need to configure your firewall to allow specific websites.
