In going through my list of tweaks I have discovered the Removing The Search ‘Go’ Button tweak does not work with Firefox 3. If you have found a way to remove the Search Magnifying Glass, please Contact The Guru so I can update this for our fellow Firefox 3 users.
I am still having troubles removing the address bar ‘Go Button’, which now only shows up if there is not an address in the address bar. While looking for a solution for that issue I came across Early Adopters: Your Firefox 3 chrome tweaks are HERE. Turns out the string in UserChrome.css has changed slightly. Here is the text you need to copy into your UserChrome.css file:
/*Remove the search button (magnifying glass) */
.search-go-button { display: none !important; }

Thanks! Just what I was looking for.
Incase you don’t have this one yet.
Remove the RSS Feed Subscribe button from the address bar.
#feed-button { display: none !important;}}
