This Add-on's got you covered with totally customizable sets of buttons and menus settings, on an additional toolbar, which you can hide away.

Easy quick-access to all those well-hidden settings in Firefox' bowels is possible, with this great Add-on - you can even write and perform Javascript actions for them.

Accessing and toggling Geo API, Social API, Observer API, Timing API, Reporting, Media API, Cookies, HTTP- and HTTPS-Referrers, Fonts, WebGL, AsmJS, GFX, Canvas, Tweaks......

Everthing you can manipulate in "about:config" or in the settings menu, you can also control with this great tool!

Vote for Mozilla extending the WebExtensions API in a way, that Add-ons like this one can be still be used in the future - or else...
