Some Firefox extensions I use:

  • Show Failed URL puts the URL in the location bar instead of the XUL error page. I still have trouble with the Back button when there are errors, though.
  • Tabbrowser Preferences lets me change some (but not all) new windows to open in new tabs instead. It has some other tab options as well. I also like Petite Tabbrowser Extensions, but it doesn’t seem to let me make external links in new tabs instead of new windows.
  • Flat Bookmark Editing is something I loved in Galeon and missed in Firefox. This extension gives me sane bookmark management in Firefox.
  • Target Alert is something I tried setting up manually (using userContent.css), but the extension is more polished.
  • DOM Inspector lets me look at the DOM tree of any page. I don’t use this very much.
