I think I've fixed a problem with my Mozilla Firefox browser.
I have version 52.0.1
My Advanced System care was giving warnings of 100% disk usage by Firefox.
Firefox was hammering my Hard Disk.
It was writing Gigabytes to the hard disk all the time.
After some internet searches I came up with a solution:

change the address bar from
about:preferences#generalto
about:configIt will come up with a screen saying
"this might void your warranty" ( only a joke )
click - I accept the risk.
browser.cache.disk.enable and set it to false
by double clicking on it.
then set
browser.cache.memory.enable to true
then change:
browser.sessionstore.resume_from_crash to FALSE
I am no longer getting constant 100% usage of the HDD.
The way it was going it would have trashed my HDD eventually.
Another solution would be to ditch Firefox & use Google Chrome.
