I left a preliminary review before, and this has turned out to be as good as predicted. However I would still like to see
1. Syncing with firefox account or save option
2. Ability to reload current tab in container or to convert current tab to a container tab.
3. More flexibility with moving items on the list of containers
4. Integration with tabs + button so you can choose which tab to open from there.
5. More colors/Flexible color choices
Great job. Such a good idea!

no more use multi-profile firefox, just multi-account container solve it.
thanks a lot

Very good at keeping identities separate.
I would find it very useful if the Default Container could be a tab in a Private Window.

Google Chrome accounts are more straightforward to use, there is no sense in discussing this.
Containers on Firefox are more useful though. They take some use to it, tabs do not sync over (Desktop) devices but enable you to make much more than just accounts. If you take privacy seriously, this is the way to go.

It was better during the Test Pilot. So many features are missing now.

L'UX peut encore être améliorée et il y a des fois où c'est légèrement contraignant, mais déjà un outil utile

very good. work not fine and I cannot open the first page on firefox start in Personal area of the Add-On.

Semplicità

+Exactly what I needed!
- Doesn't have keyboard shortcuts

Great idea and nice implementation! However, unfortunately, add-on configuration is not synced over to other browsers, so one had to manually configure it everywhere.

Great addon, finally I can isolate all the ads about things I have bought already in a separate space and isolate Google from my life (well, maybe).
But still needs polishing - e.g. if I save image from a protected page in a Work container (e.g. Jira), is seems to be saved using the default containerm where I have no Jira login and as a result I get a login html instead of my image...

I like the ability to isolate different types of browsing in separate containers.
I would like to be able to move a tab from the default container to a specific one. This would simplify registering a site with a container.
I would like to be able to select custom icons and colors for my containers.

Awesome add-on. Pretty easy to configure and I really like that websites can be set to open by default in a specific container. What would really make it a 5-star add-on for me, would be built-in automatic sync for settings across devices for the Firefox account.

Pretty good extension, but doesn't work with all websites.

I always have to re-login into Twitter when I closed FF and WhatsApp is always opened in the default container.

Need a way to have certain containers act as private tabs - IE it doesn't appear on your history.

Makes browsing even more more secure by separating your bank accounts infos, from your Facebook infos, from the rest. Much better than the "private" browsing concept because the cookies for each of these world remain after each browsing session, so you don't have to start over again each time. Much better also, because switching between each container is automatic (if desired), so you don't have to remember who goes where : in itself this is a great security feature. Of course, as the name implies, if you have many accounts for a given site, it also allows you to stay logged-in as these various accounts all at the same time, which is great. Loses a star because setup is not smooth, but once everything is set-up, Firefox Multi-Account Containers becomes totally transparent and a joy to use.

As the title said, this is by far the must have extension. Just a little bit uneasy to setup. But once set, everything will work like it should.

Worked as intended and quite smooth ( 2 weeks usage, as of now. No hang/slow down yet) but again syncing across devices should be a great plus

too many acounts can get very confusing, hoping to get a few utilities or tools to make the organizing easier
