I normally use Firefox, but, as I also have Seamonkey as an additional Browser, I am at present using Seamonkey to see what I can establish.
At the very top of this page there is a grey area that accomodates the tool bars. If there is a very narrow strip at the bottom of the area with a small triangle on the very left hand side, then click the triangle.
Clicking triangles alongside any one of the toolbars will remove the toolbar and place its triangle on the bottom line and it can be clicked at that point to re-instate the toolbar.
