Original Twitter Logo per nkasmanoff

Hey! Looks like on the source code for twitter, they changed the aria-label from "twitter" finally to "x". This was a breaking change as that was what I was locating for, but have replaced it now.

I'm not sure if there's a way to update the favicon and every other reference to X, but if there is a way to make an extension totally revert these changes I'd be open to feedback or get pointed to an ext that already does this.

Thanks for using this :-)
