Firefox ESR questions, answered directly.
Why use Firefox ESR instead of regular Firefox?
Firefox ESR (Extended Support Release) is the enterprise variant of Firefox with predictable update cadence: one major version every ~52 weeks rather than every 4 weeks. This makes it appropriate for enterprise environments with strict change-management processes. The CIS benchmark targets ESR specifically.
Does CISGuard support regular Firefox (not ESR)?
CISGuard supports both Firefox ESR and regular Firefox installations, but applies the CIS Firefox ESR Benchmark uniformly. Regular Firefox may receive feature changes between releases that the benchmark hasn't yet incorporated; the benchmark is most accurate when applied to ESR.
How does CISGuard validate Firefox enterprise policy?
Firefox enterprise policy is delivered via policies.json (cross-platform) or Group Policy ADMX templates (Windows). CISGuard reads the effective policy from each endpoint and validates it against the CIS-recommended baseline, reporting per-endpoint compliance status.
Often deployed together with Firefox ESR.
