I'm very interested in Custom Toolbars for web browsers. It's too bad that web sites devoted to such tools are sadly lacking in a general overview of what toolbars are, what they do, how they help both users and companies.
I hope to be able, in the near future, to offer a special Vaspers the Grate custom toolbar for my readers. I'm also investigating custom toolbars for some clients, like the W.D. Boyce Council-Boy Scouts of America.
There are many things you can do with a browser toolbar to promote your company, products, and expertise...while you help users and protect them from unwanted Flash, pop-up ads, phishing, spoofing, etc.
Check out Dynamic Toolbar 5 and its many applications for a wide variety of top companies, like Yahoo, Comcast, Verizon, etc.
