Removing Titlebar Firefox Quantum (firefox 57) Gnome 3.26 Wayland

I believe the feature is still experimental hence has not been enabled by default.

Type (without the quotation marks): “about:config” in the addressbar

Search for:
“browser.tabs.drawInTitlebar” toggle “true”
“widget.allow-client-side-decoration” toggle “true”

Restart Firefox.

There is a slim white bar at the top… doesn’t bother me
