Give us a big Back!

Some CSS to go in Firefox's userChrome.css, modified from Phil Wilson's version to work with Firefox 1.1 (the alpha build released so far, anyway):
/* Force the Back label to be visible, even in no text */
toolbar:not([mode=full]) #back-button .toolbarbutton-text {
  display: -moz-box !important;
/* Put the Back label to the right of the button */
toolbar:not([mode=full]) #back-button .toolbarbutton-menubutton-button {
  -moz-box-orient: horizontal !important;
/* Put some spacing around the Back button icon */
toolbar:not([mode=full]) #back-button .toolbarbutton-icon { 
  margin-left: 8px; 
  margin-right: 8px; 
/* Remove Forward button when there's nothing to go forward to */
#forward-button[disabled="true"] { display: none; }

For Firefox 1.0, just replace 'margin-' with 'padding-'.

Big Back
