Resolved: Unable to access firewall management using Chrome v80
As of 2/13/2020 Chrome has updated to version 80.0.3987.106 which no longer causes issues with firewall management.
Our engineering teams are working on this issue to provide a resolution to customers who use Chrome as a preferred browser.
At this time the confirmed workaround is to use an alternative browser such as Microsoft IE or Mozilla Firefox (to name a few).
This article will be updated when further information becomes available.
