Never used it as I avoid all the excess baggage of multiple toolbars, but
probably someone here can help you.

Question: are you sure it is compatible with Ubuntu? It should tell you when
you try to install it and if it's not going in maybe it just hasn't been
adapted to Linux.

Why would you need Adobe toolbar? You can read pdfs without it. You can
print to pdf without it. What does it offer that can't be found elsewhere?

When you ask for help, it is a good idea to provide links to said toolbar.

Maybe you could expand on what the Adobe ToolBar is!

Are you by any chance thinking of the Yahoo ToolBar from Adobe? Or
the Adobe Acrobat Toolbar from Acrobat Version 5/6?
