I’m setting up Android kiosk mode on Samsung tablets and need Firefox to run a web app. Under Website Kiosk settings, I selected Firefox as the browser, but the option to add websites to the allowlist is greyed out.
The web app does not display correctly in Chrome or Hexnode Kiosk Browser, so switching browsers is not ideal. Is the website allowlist feature only supported with Hexnode Kiosk Browser, or is there another way to restrict Firefox to approved sites while the device is in kiosk mode?

The website allowlist option under Website Kiosk is available only when Hexnode Kiosk Browser is used as the kiosk browser. If Firefox is selected, the Add button for the Website Kiosk allowlist will remain disabled.

For Samsung devices, you can use Samsung Knox native Web Content Filtering as an alternative. This lets you configure an allowlist at the device policy level while continuing to use Firefox as the kiosk app.

General approach:

  1. Add Firefox as the allowed app in the Android kiosk policy.
  2. Configure Samsung Knox Web Content Filtering in the Android policy.
  3. Add the required web app URLs to the allowlist.
  4. Associate the policy with the Samsung devices.

This option requires a supported Samsung Knox device running Android 6.0 or later with Knox version 2.6 or above, corresponding to Knox API level 19 or higher.
