The preferences page for Download them all is not working in SeaMonkey 1.0

The preferences page for Download them all is not working in SeaMonkey 1.0

This is because of the absence of an add-on called x-sidebar in SeaMonkey. Before installing Download them all add-on in SeaMonkey, you must install an add-on called X-sidebar which can be installed from addons.mozilla.org.

If you have already installed download them all, no worries, just install the X-sidebar add-on and then the preferences page will work for download them all.
