Issue:
When we access the NFA console using the Firefox browser, there are some issues with regards to the appearance of some pages, I'm attaching a snapshot from the enable interfaces page. It does have all the info but one can't see it. When we use chrome everything is fine. Until a few days back it was fine.
Environment:
NFA 9.3.*
Windows 2012
Cause:
Problem between last  Firefox versions (60 and up)  and Adobe Flash
Resolution:
disable the hardware acceleration in flash doing :
 open the NFA enabled interfaces page in Firefox
  righ click keeping the mouse in the screen center
  start settings
  click on the first left icon
  unselect the hardware acceleration box
  click the close button
  refresh the page
