Troubleshooting: Browser Cannot Download Files

Symptom

You are trying to view or download a file with the browser, but you get error messages instead.

Problem

The browser has no permissions for the file path you have selected for download. This is because the Firefox browser is being guarded by AppArmor for security reasons. 

Solution

Check whether one of the following possibilities for downloading files is applicable/available:

• Storage hotplug device (USB flash drive) which is mounted to /media/[device name] or /userhome/media/[device name]
  For hotplug storage configuration, see Storage Hotplug.

• Network drive which is mounted to /mnt/[folder name]

• Folder /userhome in the local file system; not persistent
