Caching of dynamic content is enabled by default in all squid-3.1 and later.

If you have a squid.conf configured using settings imported from older
versions or from documented written for older versions please start with
a review of your use of "cache " directive and remove the QUERY ACL.
Then ensure you have the new default cgi-bin refresh_pattern:
<http://wiki.squid-cache.org/SquidFaq/ConfiguringSquid#Do_you_have_a_squid.conf_example.3F>

In regards to the particular examples you ask about; both of those sites
content is cacheable and are already cached by Squid.

* facebook the only problem is the HTTPS encryption. Removing that
encryption and/or forcing caching is a direct violation of the end users
privacy rights and often illegal, YHBW.

* youtube the content distribution by design and with active enforcement
from the publisher/copyright holder uses methodology preventing optimal
cache usage. The Store-ID feature can be used to de-duplicate a certain
amount of content duplication caused as a result of that design. But
only up to a point.
