update on this problem: deleting the xulstore.json file didnt still fixed the issue but i found something related to that file, i found out a piece of extra code thats being added to xulstore.json file that causes this problem and that code is "sidebar-box":{"sidebarcommand":"","style":""},"sidebar-title":{"value":""}}
