Perhaps it's a flash issue?

With out flash enabled, top shows seamonkey-bin taking 2.3% cpu & 20.3%
memory. This is running Ubuntu 11.10, has a P4 2.4Ghz processor, 3GB of
memory (1GB of that is taken up by a virtual machine just now).
about:support shows:

Graphics
Adapter Description: NVIDIA Corporation -- Quadro4 900 XGL/AGP/SSE2
Vendor ID: NVIDIA Corporation
Device ID: Quadro4 900 XGL/AGP/SSE2
Driver Version: 1.5.8 NVIDIA 96.43.20
WebGL Renderer: Blocked for your graphics card because of unresolved
driver issues.
GPU Accelerated Windows: 0. Blocked for your graphics card because of
unresolved driver issues.
AzureBackend: skia

You can't get much more basic than that.

Now lets reload that page with flash turned on:
top showed the cpu jumping to 16.9% and nearly immediately going back
down to ~9-10%. Cick on 'View Virtual Tour' & no noticeable differenct.

Further, I've been running this 2.9.1 SM all day w/2 windows & 15
browsing tabs, standard email window + 3 nntp windows open. So it might
be worthwhile to explore other issues with your system/graphics?
