Not very customizable Rated 1 out of 5 stars
One thing I love with most Firefix toolbars is the ability to remove certain things in the toolbar itself, or move the toolbar & combine it in another toolbar. The Yahoo toolbar does not allow that. I don't want or use the Yahoo Search bar but I can't remove it, and I can't add anything else to the row the toolbar takes up.
So far, I haven't really found any alternatives to it, but I am looking.
