I was saddened to see this stop working, as it has been my favorite add-on since it was first published. For those like me that miss it, I can verify that the Fixed version published by David White at https://addons.mozilla.org/en-US/firefox/addon/googlebar-fixed/ does in fact work, and after comparing the source code, it is clear that there are no hidden changes in the code.
