Loading of system homepage is broken when Tor is enabled on start
If a system-wide homepage is set in Firefox, when Torbutton is installed and Tor enabled on start, the homepage is unfortunately not shown.
The patch available at http://patch-tracker.debian.org/patch/series/view/torbutton/1.4.0-2/fix-loading-of-system-homepage.patch fix the issue by looking up at the .properties file if needed.
