Недавно я перенес все свои профили Firefox до последней версии 58.0.2.
Для некоторых профилей пользовательская панель инструментов, которую я использовал до FF57 +, теперь исчезла. Я думаю, что эта пользовательская панель инструментов была добавлена устаревшим расширением: Classic Theme Restorer. Так как это расширение больше не поддерживается в FF57 +, панель инструментов исчезла, что нормально.
Но в некоторых профилях я увидел, что моя пользовательская панель инструментов все еще здесь: 
Моя пользовательская панель инструментов содержит красный значок AdBlock Plus (среди прочих).
Это дает мне надежду. Это ясно указывает на то, что пользовательская панель инструментов по-прежнему реализована, хотя мы не можем создать ее непосредственно из графического интерфейса. Я проверил browser.uiCustomization.stateпараметр в about:config:

Мы видим, что на пользовательскую панель инструментов «__customToolbar_Syl» все еще ссылаются (что не относится к профилям без моей пользовательской панели инструментов).

Я пытался вставить свою пользовательскую панель инструментов в другой профиль (в "места размещения" и "dirtyAreaCache"), но это не сработало. Каждый раз, когда Firefox перезапускается, панель инструментов удаляется из browser.uiCustomization.stateпараметра. Я не понимаю, почему в некоторых профилях моя пользовательская панель инструментов никогда не удаляется, а в других - почему. Я надеюсь, что Firefox даст возможность создать собственную панель инструментов в следующих выпусках. Иначе, где мы сможем разместить все кнопки / значки расширения? На данный момент я помещаю их в панель инструментов меню, но это не идеально (на скриншоте вы видите очень мало значков расширений, так как это тестовый профиль. В моих производственных профилях у меня более 100 расширений ...)
Mozilla не дает абсолютно никакой документации по этому параметру. Например, я обнаружил, что могу вставлять пользовательские разделители в разные панели инструментов, используя browser.uiCustomization.stateпараметр.
Я также создал запрос в службу поддержки на support.mozilla.org.
