When downloading an executable file in Firefox (26) windows shows the "File Access - Security warning". Since I am not stupid and don't try to execute downloaded files I don't trust and clearly don't need to be asked again every time I download something I'd like to disable this annoying warning.
How to get rid of the File Access Security Warning for EXEs downloaded with Firefox 26+?
For when setting
false doesn't seem to work, one can try applying the following
Windows Registry Editor Version 5.00 ; Do not preserve zone information in file attachments [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Attachments] "SaveZoneInformation"=dword:00000001
Verified to work on Firefox 31, without rebooting the system, and even without restarting Firefox.
For information on the
SaveZoneInformation Group Policy registry setting, see https://support.microsoft.com/kb/883260.
As mentioned in this bugzilla entry, there is a new
about:config option that controls this behavior. Setting
false disables it.
