  1. Open a new Firefox tab

Notes
  • This is a workaround for customers who are still on Authentication Manager 8.1 pre SP1 Patch 2.
  • Also new deployments before applying updates.
  • If their Firefox version is new, or updated.
  • If they can't enable SSLv3.
Another workaround is to download a standalone older version of Firefox, using the link to Firefox 35 standalone.
