Make sure to disable container sync when using this combination. It's easy to accumulate hundreds of temporary containers which somehow hoses your Firefox profile on Mozilla's sync server (and can also produce gigabytes of logs in your local profile directory). It seems it's currently impossible to recover your profile once you reach "Maximum bytes per object exceeded" - the remote end won't even let you delete the offending data.

In Google sued for secretly amassing vast trove of user data
I didn't see multi-account containers mentioned: https://github.com/mozilla/multi-account-containers#readme That one changed my life. It allows me to log into different AWS accounts at the same time. Also different Gmail accounts at once (like my kids' email and mine). Also it gives you a massive boost in privacy since cookies don't follow you around since they are restricted to one container. Combined with Container Tabs Sidebar: https://github.com/maciekmm/container-tabs-sidebar You get the tree style tabs with automatic organization by container.
In Firefox extensions to make remote work and school a little better
I love this feature... on one machine at a time. Without a built-in sync feature, I continue to use the simplest form of cookie management: Private Windows. I know there's been some discussion on sync: https://github.com/mozilla/multi-account-containers/issues/3.... As of Dec 2019, it looks like some traction will be coming to syncing just Containers and Site Assignments (which I believe would perfectly suffice most basic needs). If anyone really wanted to keep an eye on sync, I'm guessing these features will be committed to their syncserver, when available: https://github.com/mozilla-services/syncserver.
In Firefox Multi-Account Containers
This a really useful extension for working with multiple cloud service accounts (e.g. AWS assumes a global session, GCP theoretically supports multiple logins but it's in the usual Google NOQA zone where many things break) but there's a really important limitation to know about: the container configuration isn't synchronized with your account. This means that if anything reset your Firefox profile (like that bug they had last year) or if you use multiple computers, you'll be spending a lot of time duplicating the configuration: See https://github.com/mozilla/multi-account-containers/issues/3...
In Firefox Multi-Account Containers
(3 months ago) https://github.com/mozilla/multi-account-containers/issues/3... > With #1537, our next release starts to address container-bookmark integration & UX. As @MichaelTunnell points out, it does not solve ALL of the container-bookmark UX requests in this issue, or in #854 #1142 and #1443. > Container-bookmark UX is a big project, and some of the solutions will require changes in Firefox itself. Any changes here could introduce tricky bugs both in technical integration and in UX flows.
