Show Desktop Ctrl-Alt-D stopped working for Firefox only

[virtual reality]

Hi,

I don't know why but

show Desktop Ctrl-Alt-D suddenly stopped working for Firefox only (in all workspaces).

:(

Any ideas what might have caused this? Any work-arounds? (apart from Ctrl-Alt-(arrow) / switching to a different workspace - which is a fair workaround)

thx,

vr.

I'm having this issue too. Sucks, I use Ctrl-Alt-D all the time.

UPDATE - Here's the solution:
