My laptop computer has at the top of the usable screen space in the Mozilla Firefox browser window are two horizontal strips - I suppose they are called Toolbars.
The lower one includes the exhortation to "Upgrade to the latest Yahoo Toolbar and the one above says "Customize links, Free Hotmail, Windows, Windows Media"
How do I remove these strips (toolbars?)
Apart from the fact I did not know Hotmail had been incarcerated and required freeing, I dislike having to see US Microsoftised English spelling for "Customerise", even if Spellcheck cannot spell ordinary English words.
