My userChrome.css doesn’t seem to be doing what it did previously, and the text in my URL-bar is far too small. Here’s what fixed it in my userChrome.css previously: #urlbar {-moz-appearance: none !important; font-family: Tahoma Bold !important; color: Black !important; font-size: 16pt !important; } but it doesn’t seem to be doing anything now; change the font-size and restarting Firefox doesn’t seem to make any difference. Why is it behaving differently now?

I export to HTML fairly often with orgmode. In this case “export and open” resulting in viewing the code is almost never what I want; it would be much more useful like the export pdf option, which doesn’t view to the LaTeX code but right to the PDF. Answer As per https://emacs.stackexchange.com/questions/2387/browser-not-opening-when-exporting-html-from-org-mode A setting change fixed this. M-x customize-variable org-file-apps and for files of type \\.x?html?\\' I specified firefox %s. Now it does what I want.
