The Firefox ESR app in IGEL OS provides an enterprise-ready web browser based on Mozilla’s Extended Support Release (ESR) channel. The ESR channel offers long-term support and predictable update cycles, making it suitable for managed environments that require stability and controlled feature changes.
The Firefox ESR app can be centrally configured using the IGEL Universal Management Suite (UMS). Administrators can define browser behavior, starting methods, policies, and security-related settings via UMS profiles. This ensures consistent configuration and policy enforcement across all assigned devices.
