It is no wonder why the user base of the Mozilla Foundation developed Firefox browser is up 39%; there are so many customization options out there to fit the tastes and needs of any user. Two new customization options have come to light and we are more than happy to present them to use so as to further increase your user experience.

Whenever your Firefox window is not maximized, you will notice a small, spotted triangle in the bottom right corner. The purpose of that depiction 9i do not really know what it is called) is to inform you that by clicking and holding down the mouse button you can resize the window – which is really redundant because you can grab the window by any other side and resize the window. Since it serves no other purpose than to take up space in the status bar, you could remove it; and the simplest way to do so is with Stylish.
Once you get the Stylish add-on, you must insert the following:

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);

.statusbar-resizerpanel {
-moz-appearance: none !important;
display: none !important; }

Moving on, you might want to keep having access to the usefulness of the Menubar but without having to constantly see it in your Firefox window. A small reminder first: the Menubar is that piece of window real-estate where you see File, Edit, History, Help, and so on. Once you get the Hide Menubar add-on that menu will be automatically be hidden from view; to bring it back into focus just press Alt on your keyboard. Hide Menubar only works with Firefox 3.0 versions and upward. If you are using anything else, like Firefox 2.0.0.19, you are out of luck twofold: no Mozilla support and no way of running this nifty little add-on.
