We know this is old news for some, but nevertheless important. Google has discontinued it's Labs program, which means that the Google Toolbar will not be supported going forward. The company is trying to focus it's efforts on primary tools and initiatives, rather than spread itself too thin.

Google claims the capabilities of the Google Toolbar can be found elsewhere, which is true. The problem is that none of the other options currently offer the same level of ease for doing things like: site search, finding a website's Pagerank or quick access buttons to other handy Google services for heavy Google users.

Yes, there are quite a bit of good SEO toolbars out there, which can show Pagerank for a domain or web page, but the all-in-one Google access is a bit harder to come by.  Some have suggested that by dropping the Google Toolbar and thus reducing one of the most popular Firefox add-ons, Google is clearly pushing users to it's own browser instead--certainly there is some truth to this.
