OK, narrowing things down, the problematic site is http://anisama.tv
with noscript set to allow anisama.tv, twitter.com and twimg.com
The add-on rikaichan was enabled but was not being used to look up
Japanese text that the page was displaying.
To get a relatively clean load, I did a kill -HUP on the iceweasel
process, then when it prompted to restore tabs, I opened a new tab and
opened the site http://anisama.tv then let it run until the icewaasel
process had consumed 1 minute of CPU time. Memory use increased while
the site anisama.tv was open. If needed I could leave it running for
longer and post another about:memory
During the course of waking ours in Japan the site anisama.tv seems to
display many tweets but even so it shouldn't be consuming several
gigabytes per day.
Thanks for your help with this.
