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.

[…] Removing The Search ‘Go’ Button – Removing the ‘Go’ buttons for the address bar and the search bar turned out to be a bit of challenge in Firefox 3. […]
How do I remove ANY button. I haven’t been able to do so.
A related but sort of opposite Firefox 3 (v3.5.7, actually) wish: I like clicking to start a search – don’t enjoy tapping the ENTER key. I don’t want to get rid of a clickable “do it”-type icon, I want to have one there all the time. Maybe the proverbial magnifying glass, maybe a GO button – don’t care. Either inside the searchbar field or next to it.
As it is now, I never see one at any time. Unfortunately I can’t recall whether I ever did anything to get rid of one when I first got Firefox 3. Looking all over the web I can’t even tell whether Firefox 3 was supposed to have one as standard. And I haven’t located any relevant setting, userscript, option, extension, or about:config alteration among my Firefox 3 nooks and crannies. I was hoping this blog’s author or a reader would have a suggestion on how to absolutely/positively put one in?
