How do I show the bookmarks toolbar while in fullscreen on Firefox 20? In older versions you could edit the userChrome.css file. Does that still exist?

Question

After searching for this option, it appears it was very easy to do in older versions of firefox on windows 7. Many posts say you can edit the userChrome.css file to add:
#PersonalToolbar[moz-collapsed="true"] {
visibility: visible !important;
However, on 2 machines with firefox 20, I've searched for that file and cannot find it. Does it even exist any more? if not, how can I set firefox to go to fullscreen mode and continue to show the bookmarks toolbar? Unchecking hide toolbars does not work for the bookmarks toolbar.

Answer 1

userChrome.css does not exist by default. You can create it; it's an ordinary text file. Note that you do need a namespace at the beginning of the file.
You could try this:
@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
#PersonalToolbar[moz-collapsed="true"]{
visibility: visible !important;
#navigator-toolbox[inFullscreen="true"]{
margin-top:-62px !important;
I added the second rule to prevents the toolbar area from rolling all the way up. The specific value may need to be adjusted by a few pixels depending on your toolbar heights.
