Today, for the first time, I noticed a process named "Web Content".
I was running top because firefox was once again not allowing me to scroll.
Having been down this road before,
I would normally have just closed and reopened firefox.
I needed to do it fairly often.
Web Content was new.
Eventually, I discovered "electrolysis" (why that name?) and the schedule:
https://wiki.mozilla.org/Electrolysis#Schedule_and_Status ,
but I'm not sure how to read it.
What the heck is "riding trains"?
My firefox is 52.2.0 64-bit.
yum.log says it was last updated on the 16th.

As is unusual, I had a pretty good idea which tabs were
using up the CPU, so getting scrolling back was not too hard,
but my usual close and reopen did not work.
Is this a new "feature" of firefox?
Will close and reopen consistently fail to resolve CPU-burning issues?
Will I have to go on a tab-hunt every time?
