Merge Firefox Toolbars to get more space

I have read about a great tip at Make Use Of describing the possibility to merge Firefox toolbars to save space on the screen. I was not aware that this is possible until know. I surely removed some items on toolbars that I did not needed but I never came up with the idea to merge toolbars instead.

Until now I simply enabled toolbars whenever I needed them and disabled them again afterwards. To merge toolbars simply do the following. Enable all toolbars, right-click one of them and select customize from the menu. Now drag and drop all items that you need into one toolbar. This can be the menu bar or navigation toolbar as well.

I moved the Pagerank checker from the Google toolbar to my menu toolbar. This was actually the only useful aspect of the Google Toolbar. I thought about moving the Stumbleupon icons to the menu toolbar as well but this would reduce the input fields of the address to much.
