Since the automatic upgrade from 10.0.2 Firefox ignores the gnome-proxy-settings and so could not find the way to the Internet.
When I set the proxy-settings manual it works. It also works with the Chrome-Browser. Websites inside our network work.

You could reproduce it by:
Set the systemwide proxy-settings in gnome.
Change your proxy-settings in firefox: Edit > Preferences > Network > Settings > "Use system proxy settings"
Only internal websites works with this configuration...
To get them working you have to set the settings manual in: Edit > Preferences > Network > Settings > "Manual proxy configuration"
