The toolbars at the top of your web browser allow you to access actions such as reloading a page, stopping a webpage from loading or even printing a page. It is relatively easy to customise these toolbars to ensure actions you use frequently are displayed and those that you don't often use are removed. Here's how to customise the browser toolbar in Firefox 4.
Right-click in a free area in the Tab strip and select Customize.
From the Window that appears, simply drag and drop any icons that you want to appear in your browser to the relevant toolbar. You can also remove any icons by dragging then from the toolbar to window containing all the icons. Furthermore, you can rearrange icons by simply dragging them to a new position on the toolbar. Press Done.
