gsettings-desktop-schemas: GSettings desktop-wide schemas Details: USN-1400-1 fixed vulnerabilities in Firefox. Firefox 11 started using GSettings to access the system proxy settings. If there is a GSettings proxy settings schema, Firefox will consume it. The GSettings proxy settings schema that was shipped by default was unused by other applications and broke Firefox"s ability to use system proxy settings. This update removes the unused schema. We apologize for the inconvenience. Original advisory Firefox"s ability to use system proxy settings regressed.
