Always show the Go button in Firefox 3

In Firefox 3, the Go button only shows up when you’re typing in the Location bar. You can show the Go button permanently by following these instructions.

1. Open the folder that contains your Firefox profile (if you don’t know where that is you can read this page in the Mozillazine Knowledge Base).
2. Look for a directory named chrome and open it. If the directory does not exist, create it.
3. Open the file called userChrome.css. If the file does not exist, create a blank text file and call it userChrome.css.
4. Make sure that the following is the first line of the file (taken from the file \chrome\userChrome-example.css):
   

   @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

5. At the end of the file, add the following line:
   

   #urlbar[pageproxystate="valid"] > #urlbar-icons > #go-button { visibility: visible !important;} /* Show the Go button permanently in the location bar */

6. Restart Firefox.
