Is your browser version compatible with the latest technology?

Topic summary

Issue: Users on Firefox ESR receive “browser not up to date” warnings despite running the latest available ESR version.

Context: Firefox has two release channels—Rapid Release and ESR (Extended Support Release). ESR updates on a slower cadence focused on security/stability, so its version number may lag Rapid Release while still being current and supported.

Request: Update the technology/compatibility checks to recognize and differentiate ESR from Rapid Release, preventing false alerts for up-to-date ESR installations.

Action item: Adjust version-detection logic to validate against Mozilla’s ESR release information and treat current ESR versions as supported.

Status: No resolution or confirmation yet; discussion remains open.

Open questions: Whether ESR is officially supported by the service, and what minimum ESR version is required, if any.

We are receiving notifications that our Browser is not up to date and could potentially cause problems. We are using Firefox esr and have checked that we are on the latest available version. Please update your technology to differentiate between the “rapid release” and the “esr” versions.

Thank you,

John
