re:freezing screen with Ubuntu 16.04

This only started recently with me, after watching in the monitor I noticed the process Web Content was taking almost all the CPU time and a lot of memory until I ran out of my 6 GB.

I solved it by using these following procedures, after removing a Cookie editor extension:

#1 Under Firefox pref: Accept 3rd party cookies only from visited websites!

#2 change this in GRUB

    There is a line in that: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" (like this), replace with: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"

#3 My SWAP was not being used at all! I doubled my swap space to that of my memory (12 GB)

Would still freeze or run very slow, finally solved with this:

#4 I installed noscript from Firefox/Tools/extensions and only allow a select few site to run scripts.
