make sidebar/address bar rounded corner toggleable

[JamesHill]

I am currently using firefox nightly for the sidebar/vertical tabs. The corner where the sidebar intersects with the address bar is rounded, but I don't want it to be. I would like to have this be optional. below is the spot I am referring to.

You already can do that by enabling sidebar.revamp.round-content-area in the about:config
