Mozilla Firefox Freezes on Windows 10 computer

Therefore I have been using mozilla firefox freezing up Quantum for a little while today, so far it's been fantastic.
Lately firefox freezing up was behaving. I do not actually know precisely when, but it's likely under a month because this problems showed up.
I do not exactly understand what's causing the issue. Every now and then, Mozilla firefox freezing would only freeze for some time. I must wait till it unfreezes to be able to do anything .
It occurs fairly regularly on youtube, in which the movie only freezes (although the sound is acting good ) and now I must wait around for a little to have the video gets moving again.
However, I understand this is not a movie just issue. Even easy tabs freeze up sometimes. I'd occasionally click on a folder use the ctrl+tab to browse around, however shifting tabs will hang every now and then. Once I click a folder, firefox freezes up pops up for several minutes before it eventually moves into a new tab.
The 1 thing that I noticed is that if this occurs, the CPU utilization spikes a little bit. It typically sits at approximately 9% to 15 percent based what I am doing (being around reddit, or viewing movies on youtube), however if this freeze occurs, the CPU usage will spike up to 60 percent. My CPU is a i7-6700hq skylake notebook CPU, using a GTX 1060 GPU.
So far I've tried:
