Advisory: Application Pages Do Not Load on Firefox v80
Posted by Aly Essa, Last modified by Aly Essa on 10 September 2020 11:34 AM

A recent update to the Firefox framework introduced behaviour where the sessionStorage information no longer persists across new tabs created by our web applications. For example, new tabs are created with the activity views and Server log pages. Because of the new lack of persistence, our web applications experience issues when attempting to authenticate WebSocket connections with the underlying WebServers. These issues cause the customer's pages to properly load, which then leads to unusable pages.


Firefox v80
FileCatalyst Central 
FileCatalyst Server 
FileCatalyst HotFolder 
FileCatalyst TransferAgent 

Note: For the FileCatalyst Application listed above you could encounter this issue while running v3.7.2 to v3.8.


A downgrade of Firefox to a lower version (tested with 77.0) or you can use alternative browsers that we support (Chrome and Edge). Doing so will allow you to successfully view pages that are created in tabs that are produced by our applications.

Our aim is to have this issue resolved in a future build of the products listed above as soon as possible.
