Thank you Joe Z, Tim and Richard E.
Firefox just starting freezing.

Note that I do not have disk swap.
I expect the above is at least partly a computation involving zswap.
about:performance takes me to about:processes .
Main, google and yahoo mail tabs seem to be taking the most CPU and memory,
20% 618MB, 0.6% 411MG and 0.18% 159MB .
The latter two occasionally flicker to about 20% CPU.
No smoking gun.

Apparently there is a tree for each tab.
I have a lot of tabs.
This took me about an hour.
When firefox is frozen, I cannot scroll it nor copy from it.
I have to wait for a good second.
Firefox does not take gnome with it.
