You must provide a valid URL. Could not fetch usable data.

http://www.youtube.com seems to be valid URL

That is not what a URL alias is for.

A URL alias is pointed to a file that contains IP or IP/CIDR alias data, it does not refer to a website URL to block/pass.

Ops now I'm confused.

Enter a single URL containing a large number of IPs and/or Subnets. After saving pfSense will download the URL and create a table file containing these addresses. This will work with large numbers of addresses (30,000+) or small numbers

name:youtube
type:URL Table
URL:http://youtube.com
Update Freq:32

Read the note again. It says enter a URL containing a large number of IPs and/or subnets – nowhere in that note does it refer to blocking/passing that URL.

It says it will download the URL and create a table of the IPs and/or Subnets contained in the data downloaded from that URL.

I can add some more text to that note to make it clearer, but you cannot use "http://www.google.com" in any alias type in pfSense and expect it to work.

It's meant to work on a file like this:
http://files.pfsense.org/US_cidr.txt

Ah ok I get it.
I thought this purpose is to take the dynamic DNS ip's and update it frequently.

No, for that just use a normal host or network alias and type in the hostname, www.google.com (no http://). The hostname will be resolved and updated internally periodically.
