Some client settings are synchronized, the theme in this case.
This allows server rendered applications to look the same as other local
applications on the client.

That seems to cause problems with Firefox.
Is the "elementary" theme installed on the server?
If not, Firefox should be falling back to a default theme.
(or maybe we shouldn't be setting the theme to one that is not installed
- though I am unsure how we would check and filter that..)
If it is, then it is missing "list-add", which would be a bug in the
theme. (not the first theme bug I've encountered)

"--xsettings=no" would disable all client to server settings
synchronization, which may workaround this particular problem.
