By design, Firefox is pretty easy to customize as far as the toolbars on the top go. You just have to right click on some empty space up there, then choose “Customize”. From there you can drag things off the Firefox toolbars or add them. Two options are not so easily edited though. That would be the “Go” button and the magnifying glass.

To remove these two, you will need to edit your UserChrome.css file and add these entries to the bottom.

Remove the Go Button:

#go-button-stack, .search-go-button-stack {
display: none !important;
}

Remove the “Search” Button:

/*Remove magnifying glass button from search box*/
.search-go-button-stack { display: none !important; }

Now when your done, restart Firefox and you now have a little more room freed up where those buttons used to be.

This is a classic Firefox 2 tip that makes me wonder if it will still exist with Firefox 3 looming around the corner?
