Amos,
How can I fix it? How do I add the "use extension_methods" option?
May not need fixing.

What is all that? Is someone trying to hack the system or what?
Someone is trying to use SIP or similar software through your proxy.
A transparently intercepting proxy may expect to see that nowdays as
more non-HTTP software are using the only unblocked port available.
If you don't use interception, then the client may be broken or your
squid may need to use extension_methods for them.
