Ich habe kürzlich alle meine Firefox-Profile auf die letzte Version 58.0.2 migriert.
Für einige Profile ist die benutzerdefinierte Symbolleiste, die ich vor FF57 + verwendet habe, jetzt nicht mehr verfügbar. Ich glaube, diese benutzerdefinierte Symbolleiste wurde von einer älteren Erweiterung erstellt: Classic Theme Restorer. Da diese Erweiterung in FF57 + nicht mehr unterstützt wird, ist die Symbolleiste weg, was normal ist.
Bei einigen Profilen sah ich jedoch, dass meine benutzerdefinierte Symbolleiste immer noch hier war: 
Meine benutzerdefinierte Symbolleiste ist die Symbolleiste, die unter anderem das rote AdBlock Plus-Symbol enthält.
Dies gab mir Hoffnung. Dies zeigt deutlich, dass die benutzerdefinierte Symbolleiste noch implementiert ist, obwohl wir sie nicht direkt über die GUI erstellen können. Ich habe den browser.uiCustomization.stateParameter überprüft in about:config:

Wir sehen, dass auf die benutzerdefinierte Symbolleiste "__customToolbar_Syl" immer noch verwiesen wird (was in den Profilen ohne meine benutzerdefinierte Symbolleiste nicht der Fall ist).
Die Struktur ist wie folgt:
{ "placements": { "widget-overflow-fixed-list":[] ,"__customToolbar_Syl":[...] => my custom toolbar ,"PersonalToolbar":[...] => bookmarks toolbar ,"nav-bar":[...] => toolbar containing the address bar ,"TabsToolbar":[...] => toolbar containing the tabs ,"toolbar-menubar":[...] => top toolbar containing the menus ,"addon-bar":[...] => this is my old toolbar at the bottom (which was used by Download Status Bar (legacy extension) ,"ctraddon_addon-bar":[...] => old toolbar of Classic Theme Restorer extension ,"ctraddon_extra-bar":[...] => old toolbar of Classic Theme Restorer extension ,"web-developer-toolbar":[...] => old toolbar of a dev extension } ,"seen":[...] ,"dirtyAreaCache":["addon-bar","PersonalToolbar","nav-bar","TabsToolbar","toolbar-menubar","PanelUI-contents","ctraddon_addon-bar","web-developer-toolbar","ctraddon_extra-bar","widget-overflow-fixed-list"] ,"currentVersion":13 ,"newElementCount":1424 }
Ich habe versucht, meine benutzerdefinierte Symbolleiste in einem anderen Profil einzufügen (in "Placements" und "dirtyAreaCache"), aber es hat nie funktioniert. Bei jedem Neustart von Firefox wird die Symbolleiste aus dem browser.uiCustomization.stateParameter entfernt. Ich verstehe nicht, warum in manchen Profilen meine benutzerdefinierte Symbolleiste nie gelöscht wird und warum sie in anderen Profilen gelöscht wird. Ich hoffe, dass Firefox in den nächsten Versionen die Möglichkeit bietet, eine benutzerdefinierte Symbolleiste zu erstellen. Wo können wir sonst alle Tasten / Symbole der Erweiterung platzieren? Für den Moment habe ich sie in die Menüleiste eingefügt, aber das ist nicht ideal (auf dem Screenshot sehen Sie sehr wenige Erweiterungssymbole, da dies ein Testprofil ist. Auf meinen Produktionsprofilen habe ich mehr als 100 Erweiterungen ...)
Mozilla gibt zu diesem Parameter keinerlei Dokumentation. Ich habe zum Beispiel selbst festgestellt, dass ich mithilfe des browser.uiCustomization.stateParameters benutzerdefinierte Trennzeichen in die verschiedenen Symbolleisten einfügen kann.
Ich habe auch eine Supportanfrage in support.mozilla.org erstellt.
