OK. Well I'm another user and I tried it with three different browsers. Unfortunately, it seems to be completely broken in my primary browser, Safari, unless I use the debug menu to set the user-agent to Konq or Mac IE.
It seems to work correctly in the most recent Firebird build I have: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7a) Gecko/20040118
It also correctly displays the "Click a button to get an example text" bar in IE 5.2.3 for Mac OS X.
So I would suggest to make it do something sensible in Safari instead of being a non-operative button bar. I surmise that since it is based on the same code-base as Konqueror that it should have the same behavior on both browsers. Other than that I can't say the feature shouldn't be implemented.
However, I'm not in love with the icons. They look like buttons but don't have a "pushed" state, which is bad. Also, most of the icons are not universally recognizable and should be replaced with unambiguous text. I'm sure someone spent a long time putting those icons together, but I think most of the UI research shows that icon bars like that are almost universally inscrutable.
