Okta's Device Trust is not functional while using the Firefox browser.
- Firefox web browsers for Windows and macOS
- Okta Classic Engine
As mentioned in the Okta Device Trust solutions documentation, Device Trust requires access to the certificate store on the user's device. The Firefox browser for Windows and macOS uses an independent certificate store. Therefore, it will not work with Okta's Device Trust.
Depending on the environment settings, adding the personal certificate to Firefox can be a suitable solution. More details concerning this process can be found in external sources, such as the Install Client Digital Certificate - Firefox for Windows article.
