The following code in my userChrome.css worked perfectly fine up until this update. I can't remember which one of these two was currently working (one was a leftover from the last time it broke) but neither is working now. Does anyone know what I need to change to fix it? Bonus points if you can stop the URL bar from being rounded.

@-moz-document url(chrome://browser/content/browser.xul),
               url(chrome://browser/content/browser.xhtml) {
    .urlbar-background{
        background-color: #495056 !important;
    }
}

.urlbar-background,
#urlbar {
  background-color: #495056 !important;* 
  border-radius: 0px !important;
} 

Separately, does anyone know how to get rid of the button to the left? It's obnoxious and I want it gone. I've looked around in about:config but wasn't able to find a setting to disable it; it's possible I just missed it, though.
