Mozilla Firefox is supported with DWEX Viewer version 5.x, but some settings need to be made in Firefox when Kerberos is setup to make the connection between the SharePoint server with Dwex Portal installed and the machine with Microsoft SQL Server Analysis Services. The SharePoint server needs to be registered as a trusted and a delegation url.

For more information see

To make the necesary settings:

  1. Type "about:config" in the URL box in Firefox

  2. In the Filter box type network.negotiate

  3. For the items named network.negotiate-auth.delegation-uris and for the item network.negoatiate-auth.trusted-uris add the address of your SharePoint server or your domain. Multiple addresses should be separated by a comma.
