I got to this webpage and thought it is a nice script. I hadn't installed Greasemonkey yet. So, I installed Greasemonkey and also updated some existing addons.

After restart, the Bookmarks Toolbar was blank. Also, the page title, content and address weren't matching. It had happened before when I tried some other addon. So I disabled addons one by one till the last one. Not working... I updated to 3.0.4. Reinstalled. Uninstalled and Reinstalled, still nothing.

Then I thought, well, lets live with it. I just took customize and dragged the Bookmarks icon into the blank Bookmarks Toolbar. Yeppie... it became populated :)
