Bookmarks Toolbar "Always Show" and "Only Show" setting is broken

Hi, if you are noticing this problem in private windows (or if you have Firefox set to "Never Remember History" which makes all your windows private windows), there is a new setting for this: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button accepting the risk. ''More info on about:config:'' [[Configuration Editor for Firefox]]. ''The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.'' (2) In the search box in the page, type or paste '''browser.toolbars.bookmarks''' and pause while the list is filtered (3) Double-click the '''browser.toolbars.bookmarks.showInPrivateBrowsing''' preference to switch the value from false to true
