Some say toolbars eat up too much memory, cpu, and most importantly screen real estate. I keep mine at a minimum, with just the Google toolbar installed (for checking page rank.) What toolbar(s) is everyone using?
No toolbars but in Firefox I have one extension called SearchStatus that is very useful when I am looking for websites to buy. You can easily find number of links, whois, pagerank and so on.
I have google toolbar and ROBOFORM. Roboform is a very nice thing. It stores all my passwords and forms. It's much more usefull that the one firefox has, and when I format my hdd I copy the folder that keeps my passwords. Firefox does not have this trick.
I just started a thread about problems with what I think is the new Google toolbar, please check it out.
I dont like using toolbars except for the navigation ... for the sole reason that it takes up space in my small screen
