If I type ^Q in FF, I am currently told that I have 53 windows with

Go to URL "about:performance" for some hints about what different tabs
cost.  I'm not sure that it is accurate.

Superstition: when things get bad, quit and restart.
Model: garbage collection of something is imperfect.

Superstition: some pages are way more expensive than others -- a
simple page-count isn't a great measure

I've found that parking a page on a 'new tab' helps longevity (smile).  

Superstition: javascript eats my CPU.  Sometimes it makes my coputer's
fans sping up.  Sometimes FF tels me FF is taking a lot of CPU..
Often it is on Globe and Mail pages.

What do you mean by "renew pages"?  Is that "reload"? ^R 

I'm not sure what the 'correct' term is!!!
You've restarted your system.
You ask for FF to be started. 
Typically I have been asked if I wish to 'restore' to the previous. 
(Firefox is set to restore previous session.)

I'd take it as a sign to close tabs you don't need any longer, quit
FF, and then restart it. 

FF has already been shut down and then asked to restore. 
My question is - - -  at what point in the use of resources does FF decide to 
'not' honor the requested 'restore previous session'.
That not restore can be selective - - - if one page has a plethora of tabs - - 
such a page may 'not' be restored even if all the other pages are. 
This last iteration for me - - - - well all the pages and all the tabs were not 
restored. That was the prompt for asking about what the are.

I think that it just runs out of RAM or processor cycles. 

Hmmmmm - - - - so how many TB of ram does it take so this condition doesn't happen?
