I rarely visit sites that have Disqus with Firefox. I might once in a
while but not often. If you haven't tried that noscript yet, I'd try
it. You can install it, load a few sites you go to a lot, see what
happens and then decide if you want to keep noscript or not.
One thing I found that slowed mine down a lot, news sites that like to
reload on occasion. I'm not sure if it is the reload that does it or
something else it is doing but the noscript stopped that too.
You ever tried a new profile with no addons at all and see what it
does? That would eliminate a lot right there. I keep a test profile
just for testing things. I test some new addon or something and when
done, just delete the contents of the directory for a fresh start. This
is the command I use.
firefox %U --ProfileManager --no-remote
I have different profiles for different uses. Addons vary too.
