User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0 Build ID: 20170722072631 Steps to reproduce: Create new profile, launch it, there will be two tabs open Right click on any of them - "Bookmark All tabs" By default browser.places.useAsyncTransactions true, bug is not reproduced with browser.places.useAsyncTransactions false Actual results: Name and Folder fields are missing. Empty folder called [Folder name] is created after I press "Add bookmarks", bookmarks themselves are not saved. Expected results: Name and Folder fields are available, bookmarks are saved in desired folder after pressing "Bookmark all tabs". I attached a screenshot with ok menu vs broken menu.
