Mozilla update

This update was patched in Firefox version 84.0.2 and Firefox ESR version 78.6.1. If you are on our managed service platform datajar.mobi, this update has been tested and released to all customers with immediate effect, leveraging our Auto-Update framework.

If you have Firefox open while the patch is downloaded, you will be prompted to log out to install this as normal.
