Ubuntu :: Get A Video Download Plugin For Firefox?

I'm trying to get a video download plugin for Firefox (Ant Video) to write into a vfat partition where there's more space. I keep getting the message "You can not read or write files in this folder."

Initially, the permissions for the folder were weird. I followed the instructions here: [URL]

And edited /etc/fstab to this:

Code:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).

[Code].....
