(I first asked this question at
http://stackoverflow.com/q/39510377/1175080 and there I was suggested
to post this question to this mailing list.)
With GVim on my Windows 7 system, if I press `gx` while the cursor is on
an URL, it launches the URL in Firefox (my default browser on
Windows).
However, when I do the same on my XFCE4 Desktop on Debian 8.3 Linux
system, pressing `gx` does nothing at all.
I am using GVim (Vim 7.4) on both systems.
The `:let g:netrw_browsex_viewer` command returns `E121: Undefined variable:
g:netrw_browsex_viewer` on both systems.
I tried entering the `:let g:netrw_browsex_viewer= "xdg-open"` command on the
Linux system, but it didn't help at all.
I have two questions:
1. Why does the `gx` command work for URLs on the Windows system but
not on XFCE4 desktop on the Debian Linux system even though
`g:netrw_browsex_viewer` is undefined in both?
2. How can I make the `gx` command work for URLs on XFCE4 desktop on
the Debian Linux system?
Additional details:
1. If I run the `xdg-open http://google.com/` on shell, it launches
Google in Firefox. If there is no Firefox running, a new Firefox
instance is launched. If Firefox is already running, then a new tab
is opened in the existing instance.
2. If I enter `:call system('xdg-open http://google.com/')` from
GVim on the XFCE desktop on Debian 8.3 Linux, it launches Firefox
(or a Firefox tab) to display the URL.
3. I tried two things. I entered the
`:let g:netrw_browsex_viewer="xdg-open"` in command-line mode in Vim
itself. The gx command did nothing after that.
I also entered `let g:netrw_browsex_viewer="xdg-open"` in
~/.vimrc. The `gx` command still did not work. I have other
commands such as `colorscheme darkblue`, etc. in the same file
which work fine.
Here is the GVim version details on Windows 7 where the `gx` command
runs fine without any customization at all.

Can you help me to get the `gx` command working on the XFCE + Debian
