I would add javascript to that list - I have a cheap laptop with an Intel Atom that's my main computer at home, and the biggest thing I did to make browsing useable was install no-script, and only enable the scripted required to make a page work. It's ridiculous how badly some javascript locks pages up, on the most innocuous of pages - For example, Wikimedia pages are unusable, and lots of blogs have badly written javascript (for unknown reasons) which end-up slowing FF to a crawl. After disabling the majority of the scripts on those pages (Which aren't usually necessary to view the page anyway) things are more then usable.
