Same with me. It really does improve speed (although writing web pages without JavaScript also helps), and has many other benefits like you mention too. It can also save memory. Sometimes they add scripts to do things that some users want but I find it just gets in the way, so I disable it. CSS is less problematic, although I do sometimes disable CSS too. I also set meta refresh to manual; if a web page contains a meta refresh command, it will not refresh until I tell it to. I disabled other things too, including all third party cookies (even if they are already present).
