Disable icons in the Mozilla Firefox context menu

Modern versions of the Firefox browser have icons in the context menu for back and forward navigation commands, reload/stop command and for the "bookmark" item. Many users do not like the fact that the context menu has icons, not text labels. Besides the design, they break the user interface flow, as they are aligned horizonally while the rest of the menu items are ordered vertically. In this article, we will see how you can revert to the fully textual context menu of the Firefox browser and remove the icons.
