after applying the latest update 3p for vCenter for v6.7 (https://www.vmware.com/security/advisories/VMSA-2021-0027.html)
we are not able anymore to browse files of our datastores using vCenter in Firefox.
In vCenter, we still see all details for a datastore under the tabs summary, monitor, configure, permissions, hosts and VMs. Under tab Files just a search field is shown, nothing else. We were able to browse files of datastores with the version before, vCSA v188.8.131.52000 (3o), using identical conditions (Firefox v94.0.2 under Windows OS, always using the same user).
When logging directly in to an ESXi 6.5 or 6.7 host using web client it is possible to browse files of all datastores, as usual.
