I'm not sure I know what you mean by that.
One thing I have been doing recently is surfing with Java
and Javascript disabled in both Opera and Firefox.
Without a doubt, the vast majority of sites, including pages on Piriform, load a hell of a lot quicker for me, with Javascript disabled.
I have a Java and Javascript toggle switch on both browsers, and the only time I need to activate Javascript on Piriform, is to use the "messenger" to send a pm or make a post.
You can do both without Javascript, but I like to use rich text, which needs it enabled.
The only time I have to enable Javascript on the open web is to log in to some websites, and to view video on
some websites, but not all. Depends on the format. I can navigate from page to page quicker, and watch movies, on the DivX video sites I use with Javascript disabled no problem.
Might not be the case for everyone, but it certainly works for me.

Opera.Firefox.If it makes a difference for you, great. If not, it hasn't cost anything to try.
