Firefox & UNIX Problem

[freddy333]

On a new FreeBSD installation running xorg with xfce, after a fresh install, when attempting to run firefox from either root or a user account, firefox fails to start & returns this error - 'Error: GDK_BACKEND does not match available displays'.

 

Obviously, a display problem of some type, but I am not clear on what to do about it?

 

After extensive googling, I found a number of 'fixes' that suggest running some variation of - export DISPLAY=:0

But FreeBSD does not have an 'export' command, so this just produces a 'command not found' error.

 

Anyone know how to fix this GDK_BACKEND error for firefox on FreeBSD or Linux?

Update - It was recommended that I try firefox-esr instead of the standard firefox, so I uninstalled firefox & tried firefox-esr & it worked.

So please ignore this thread.
