I've got a headless Debian host and a Virtualbox client. Previously I was able to forward Firefox from Debian to the local box, but suddenly it just stopped working.
xterm or xeyes still work as before, no issues.
I'm trying to launch Firefox:
ssh -v -X <hostname> firefox
And the result is as follows:
/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

Any ideas?
