User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20170919220202 Steps to reproduce: I had a collection of tabs that were logged into various chat services. They were associated with a particular container (called "chats"), which had the credentials for accessing those chat services. I saved these tabs (via "Bootmarks..Bookmark All Tabs") so that I could easily reopen that collection of tabs in the future. So, I want to reopen that collection of tabs. Actual results: However, I cannot reopen them via Bookmarks.."Open all in tabs", because that does not use my "chats" container, and outside of that container, my profile does not have the credentials stored for logging into those sites. Expected results: Firefox should either: 1. Save the container tab as part of the bookmark info when saving a bookmark, and then use that container when reopening the bookmark, or 2. Offer a variant of "Open all in tabs" that opens the tab collection using a particular container tab that I select.

I've run into this problem in using Nightly 59.0a1 (2017-11-22) (64-bit). Unable to open all tabs in a container, nor am I able to open a single book mark in a container. Is there anything I can do to help move the ball forward on getting this implemented? Software QA is my background.
