Affected user here as well (Ubuntu 16.04 x86_64, all updates installed as of writing this comment). Happy to provide any debugging information needed to get this pesky bug squashed.
One other thing I noticed is that, when on the "Customise" screen, on the bottom of the window there'll be 3 buttons, specifically "Toolbars", "Themes" and "Density". Clicking on the toolbars button shows what appears to be a futile effort to display a list of possible toolbars, including the bookmarks one. It appears that the whole toolbar thing is actually broken, but the most obvious symptom is the bookmark toolbar option. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1758107 Title: View > Toolbars is Missing "Bookmarks Toolbar" Status in firefox package in Ubuntu: Confirmed Bug description: The "Bookmarks Toolbar" toggler is missing from the View > Toolbars menu in Firefox 59 on Ubuntu 16.04.4.
