[Njtechdiv] Firefox 48 inaccessible UI

[Mario]

Hello JAWS Firefox users. With the advent of Firefox version 48.0, the 
JAWS cursor can no longer read the screen, even though, in the Firefox 
configuration file:

gfx.direct2d.disabled has a value of True.
layers.acceleration.disabled has a value of True.
layers.offmainthreadcomposition.enabled has a value of False.

Has anyone heard of a new fix to get the JAWS cursor to become 
accessible in Firefox again?

Turning off hardware acceleration and checking Always use the cursor 
keys to navigate within pages doesn't seem to make a difference, but I 
think doing so does help?
