Firefox CPU usage

[Ignoramus21645]

I have noticed that many times, even with all tabs completely loaded,
Firefox eats up CPU at a rate that I find somewhat excessive, such as
70% of CPU or some such. While, possibly, some pages or extensions
create this activity, I would like to be able investigate which ones
are at fault and what exactly happens when CPU use is
excessive. Obviously, sometimes I can close pages one by one and find
out when closing one of them causes a CPU use decrease, but what I do
not know is how to investigate what is it on that page that causes
high CPU usage. Any ideas?

Steve, thanks. I will try to narrow this issue down to one page and
then will look at the elements of that page. I do use adblock
regularly, which somewhat contradicts your hypothesis, but perhaps
adblock is missing some of those ads.
