For example, I would like to open my Google calendar (set to open on FireFox sidebar) by Ctrl-Cmd-C.
Thanks.

Answer: 
No need of a Firefox add on. Just right click any bookmarks select properties and add keyword there. Now you can open your favourite site by just entering the keyword in the address bar. This post will help

But with this solution you cannot use CTRL,cmd etc.., I hope this is the closest solution to this problem!!!
Have you looked at all-in-one sidebar?

<https://addons.mozilla.org/en-US/firefox/addon/all-in-one-sidebar/>

I have not used this in years but according to the description, it has embeddable webpages in the sidebar and configurable shortcuts.

> 
> * open Bookmarks, History, Downloads, Add-ons, Page Info, Page Source, and Error Console in the sidebar
> * fully customizable toolbar at the left side of the browser
> * quickly show/hide the sidebar and the toolbar with a thin switch
> * toggle the sidebar by clicking or just by mouse movements
> * all panels are optimized for displaying in the sidebar (including slim lists)
> * place the sidebar on the left or on the right side of the browser
> * configure the behavior at the browser start or in fullscreen mode
> * MultiPanel for opening webpages in the sidebar, amongst other features
> * configurable shortcuts and additional buttons
> * third-party add-ons are supported
> * can be extensively customized

However I don't know if you can assign a shortcut to open the sidebar without a CMD/Ctrl/ etc.
