Almost Photon on Nightly

I use Firefox Nightly (2017-05-30) and Photon has been teasing us for quite a while.

Turns out that only a few changes are needed to get a pretty close look.

Photon look

I achieved this enabling the Compact Light theme and adding these rules on my userChrome.css. I only tested this on Linux.

#TabsToolbar .tab-content {
    color: white !important;
}
toolbar:-moz-lwtheme#TabsToolbar, #tabbrowser-tabs,
#TabsToolbar .scrollbutton-up,
#TabsToolbar .scrollbutton-down,
#TabsToolbar {
    background: #23327A !important;                                        
    -moz-appearance: unset !important;
}
