I'm trying to set up a preconfigured virtual machine with a particular local
file as the browser's homepage.  So I created a /etc/iceweasel/pref/local.js
with the following contents:

pref("browser.startup.homepage", "file:///root/Desktop/README.html");

When I run Iceweasel (for the first time), this setting does appear
in the "about:config" page, but the "Home" button still points at "about:".

Thanks,

Roland.

retitle 603033 Move browserconfig.properties to /etc/iceweasel
thanks

You need to set browser.startup.homepage in
/usr/lib/iceweasel/browserconfig.properties, which would thus need to be
a conffile.

Cheers,
