Why is Firefox so busy?

[Jon Kettenhofen]

One thing I have noticed is that when I restart, it seems that the sites 
don't load until I click on the page or the tab.
Once viewed, some sites will get busy loading banners, flash, youtube 
videos, etc. which will obviously slow things
down. See if that's that case.

Since you killed FF, did not exit it cleanly, I would otherwise expect 
it to revive in pretty much the same state but it
didn't.  Stuff that's real-time in memory won't be maintained unless 
written to hard drive so that may be a factor -
you killed it when you rebooted.

On the other hand!  I have had extreme issues with gnome-shell (yes the 
"new" one) gobbling up 100% to 120% or
a bit more of my hyper-threaded old xeon even with 8GB of memory, so I 
have reverted to the Classic Gnome
session which is far kinder, peaking at 50% but usually maxing out at 20 
percent and under 10 in normal use.

Like you, I am wondering where all the processor bloat comes from. I 
have removed most of my add-ons and
plug-ins to FF but with little or no effect.

I'm running Mint (14) Nadia, using the Classic Gnome session applied at 
the login.  Doesn't make me immune from
the Nasty Social Apparatus, but it beats having to reload another 
version of linux.  Cinnamon runs gnome shell.
