Why is Firefox so slow (and degrades over time)?

I have the same issue on both Win7 and Linux.

Misery loves company ;)

I suspect that part of my problem is all of the (expletive deleted)
nepomuk and akonadi garbage that most Linux distributions now seem to
force on us.  I have tried to kill off all that garbage, but it continues
to keep resurfacing and haunting me and I don't know how to totally
destroy it.
