Indeed, I understand. Its probably not worth it. What about writing a few 
modules in C in the future though?

Might have a look if I have time.

I don't really either. I have 1 gb of ram and dual core 2.1 ghz.
free says only 800 M of ram is being used, so would upgrading my ram to 2 
gb help speed when navigating?
Some times it is a little slow to respond.
It isn't using swap, lets put it that way.

Well it might be nice for quickly finding a certain link so I may look 
into this in the future, but learning python and C and don't want to learn 
another language yet to develop mozzilla products as well.

Might take a look if I get a chance.
