Google Toolbar for Firefox
This may be an old news to someones, but came as an excitement to me -- Google Toolbar for Firefox DO EXISTS (and may already been for a long while)! The download link is at here. The only thing is that it is for Firefox 1.0 - 1.4, which unfortunately does not work on my testing Firefox 1.5RC2. Well, I believe once Firefox 1.5 stable is out, they guys should be able to make it compatible to v1.5 pretty soon.
While Firefox has built in a quite fancy Google search bar, I still miss the page rank and spell check functions of Google toolbar, which to my (obviously outdated) knowledge was available for Microsoft Internet Explorer only. Well now, those who believe in Firefox are blessed ;)
