Unacceptable firefox behavior with nouveau graphics card

[Paul Goyette <paul%whooppee.com@localhost>]

It's been a couple of years now since I installed my current "GeForce 
GTX 1050 Ti" video card. It has always had "issues", especially with
firefox, and it seems to be getting worse as time goes by.  Symptoms
generally manifest themselves as long-delay hangs (up to a minute or
more, sometimes longer than my limited patience will tolerate).
During these hangs, firefox seems to behave almost normal - menus
drop down, mouse clicks on the "x" close tabs, new tabs can be
opened, etc.  But other things, such as cursor changing to a finger
when moved over a link, or trying to execute a search, or even a
simple reload-page are ignored.

As I said, this has been getting worse over time, and with a recent
update of the OS (running 10.99.4, updating from October to last week)
firefox has become almost unuseable.  I can search for things on
newegg.com but cannot display interesting results.

So, I'm looking for a few things:

1) Does this sound familiar to anyone else?  Or am I just a set-of-1 ?

2) Are there any alternatives to firefox?

3) Any recommendations on potential replacement of the video card?

Thanks in advance!
