Then lack of RAM is not the problem . . .

Based on other responses, we know what "web content" in Top
constitutes. I wish they would have unique names instead of just "web
content."  Would make things easier.  Someone said your slowness
problems is caused by library, etc. incompatibility.  I was
wondering . . .

You said you're running Firefox 62.0.3, IIRC. Did you install this
from Sid's repo or download directly from Mozilla?  I downloaded
Firefox Quantum 62.0.3 from Mozilla (tar.gz file) and installed it
manually.  Quantum isn't in the Stretch repo.  I just copied the
entire firefox directory to /opt.  (FYI: I run only Openbox with a
single LXPanel with menu.)  If you haven't done this, maybe, give it a
try. The binary has to be very generic as it's designed to run on
various versions of Linux not just Debian. Maybe, it will be more
