Theme does not hide forward button

[baco]

Using GNOME theme tweaks I've checked that the option «Always show forward button» is not checked, but the forward button still shows.

It isn't relevant. Mozilla just put #forward-button inside #urlbar-wrapper and it broken our theme. I missed this point, sorry. :(

mozilla-release (link):

<hbox id="nav-bar-customization-target">
  <toolbaritem id="urlbar-container" class="chromeclass-location" overflows="false">
    <toolbarbutton id="back-button" class="toolbarbutton-1 chromeclass-toolbar-additional"/>
    <toolbarbutton id="forward-button" class="toolbarbutton-1 chromeclass-toolbar-additional"/>
    <dummyobservertarget hidden="true"/>
    <hbox id="urlbar-wrapper">
      <textbox id="urlbar"/>

mozilla-aurora (link):

<hbox id="nav-bar-customization-target">
  <toolbaritem id="urlbar-container" class="chromeclass-location">
    <toolbarbutton id="back-button" class="toolbarbutton-1 chromeclass-toolbar-additional"/>
    <hbox id="urlbar-wrapper">
      <toolbarbutton id="forward-button" class="toolbarbutton-1 chromeclass-toolbar-additional"/>
      <textbox id="urlbar"/>

Firefox doesn't set "forwarddisabled" attribute to #urlbar-container anymore. And old behavior is impossible without them.

We have 2 choices:

1. Remove this feature (3448183).
2. Make a round button like in the default theme.
