SettingSanity is a solution to the inane removal of some of the most useful features in Firefox. It also adds the option of toolbar buttons for toggling Images and JavaScript without opening your preferences, as well as some helpful tab settings at the request of many users. Supports Firefox 56. In the meantime, after reinstalling 51.0.1, I've spent a day trying to find a good replacement that offers something similar to Classic Theme Restorer, settingsanity (both of which I 've been forced to use since the last time you decided to 'do what is best for Linux and Firefox'), cliget and Kitsune.
