In addition to disabling JavaScripts (which also removes nearly all ads), probably the "relative location bar", and the changes I made to the download dialog box (it now displays the actual URL and MIME type, and adds a "view source" option, in case it is a plain text file that the browser nevertheless wants to force downloading). These features are added using userChrome.js, and I find it useful. But what I have enabled a lot (including on HN) is user CSS. Sometimes simply disabling CSS works, but sometimes it works better to add my own additional CSS codes. (For example, on HN, I have it set up to display all comments in black, and to display vertical lines to the left of comments so that the indentation level can easily be seen. If I could make it sort everything chronologically across pages, I would have that too, but it doesn't do that.)
