Said about OmniSidebar as an alternative
JohnFastman
OmniSideBar is open-source (which All-in-One is not), reliable and highly functional. It's also more regularly updated than is All-in-One Sidebar, but offers the same functionality. I've used it for 2 years+ and never looked back.

Danilo_Venom added The Good 'ol Sidebar as an alternative to OmniSidebar
OmniSidebar is an excellent addon that allows you to place Bookmarks, Add-ons, Downloads and other frequently-used menus and space-containing stuff in a sidebar that you can access easily with a single icon button. It's especially useful if you have a decently sized screen for which you can afford to use a bit of the width to have something useful.
I have used OmniSidebar for four years and it's one of the top 7 or 8 extensions I reflexively install every time I set up Firefox.
Sadly, the developer of OmniSidebar has discontinued its development. He cites Firefox's recent (2016) commitment to web extentions rather than Addons like this (more info here: http://fasezero.com/addons/). OmniSidebar will stop working at some point in 2016 when Firefox 57 comes out. Very sad as it's an excellent little thing that makes browsing a little more convenient. No. Quite a bit more.
i really love this addons
