I want to stop some daemons from loading at boot time, specially squid3. What is the best way of doing this?

You can use the chkconfig utility for this purpose. 

sudo apt-get install chkconfig

To check the run level status of squid you can run this command: 

 chkconfig --list | grep squid

This will output something like below:

squid           0:off   1:off   2:on    3:on    4:on    5:on    6:off

To turn off squid in all run level you can use this command:

sudo chkconfig  squid off

 chkconfig --list | grep squid

squid           0:off   1:off   2:off   3:off   4:off   5:off   6:off

To turn off squid in a particular run level you can use this command:

 chkconfig  --level 3  squid off

The above answers did not work for my Ubuntu 16.04.

Here is what it worked:

sudo systemctl stop squid 
update-rc.d squid disable

sudo systemctl status squid

Although you may get an error like:

insserv: warning: current start runlevel(s) (empty) of script squid overrides LSB defaults (2 3 4 5).

insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `squid' overrides LSB defaults (0 1 6). insserv: fopen(.depend.stop): Permission denied

The service remains stopped even after reboot.

If you know why the error happens and how to fix it, please feel free to comment or edit the answer.

System daemons can use either legacy SysV init scripts or the newer Upstart.

For sysv scripts there are several management tools, one of such tools is "sysv-rc-conf" from the "sysv-rc-conf" package, install it and launch it from the terminal.

Regarding Upstart as far as I know there is no management tool yet, you need to manually rename the corresponding script from /etc/init, eg:

mv /etc/init/ufw.conf /etc/init/ufw.conf.disabled

Squid3 uses sysv init scripts, you can disable it with sysv-rc-conf .

Squid uses the old init system, so this command should do the trick: sudo update-rc.d -f squid3 remove.

For more find-grained control of when to start/stop the service: sudo sysv-rc-conf

Two the simplest ways (from my point of view).

1) mv /etc/init/squid3.conf /etc/init/squid3.conf.disabled

2) comment out the following line

start on runlevel [2345]

in /etc/init/squid3.conf
