The idea is perfect but the actual add-on could need more colors (20 would be good, at the moment the add-on has 8) and especially more icons (40 would be good, at the moment the add-on has 13). However im grateful Mozilla does us a favor with their software :)

Absolutely necessary Extention to everybody! It helps me to isolate my workspaces easily, and I don't have to think about shared cookies across different profiles!

This extension allowed me to migrate from Google Chrome and its Profiles (each one in a separate window) to Firefox... and now I can have everything in a single window.

😍 LOVE THIS! 😍 It's perfect for managing multiple AWS accounts. The GUI is a little rough but it's totally worth the functionality. Thank you!! 💗

Very helpful, would highly recommend installing it.

Very good. Need some short-cuts. Maybe the crtl+t should open a new tab of the same conteiner of the current one

muy bueno...excelente lo recomiendo !

Great Add-On! Makes my day!

Would be perfect if the option to ask to choose a container when creating a new tab by clicking on the tab bar, would also apply to the keyboard shortcut (CTRL + T)

This is a great productivity app

I love this. As containers are included in the latest nightly builds, you might want to lock this addon for new version. I do not know what happens when you install this on top of the included containers

This add-ons does not sync the tabs in chronological order as user has defined.
It should sync correctly on another device also.

Used to work, but now it keeps popping up a page asking if I want to Always Open in Assigned Container and there's no way to just reset it to default. I tried deleting the extension and reinstalling it, and now the option to create a new named container is gone! Very buggy.

Speaking of bugs, the context menu sometimes isn't there and the menu that is there (next to the URL field) locks you into the "Always Open in This Container" problem. I wish that icon wasn't there at all since this is a shared computer and the other people are likely to click on it to try to change which container they are in.

Richtig scheiße, denn das fördert Clutter und Chaos bei (zu) vielen Tabs und Fenstern:
Nach Auswahl bei einem Tab von „Always open this site in …“* öffnet sich
1. ohne Warnung/Hinweis
• ein (anscheinend) Klon des Tabs**, und zwar
• dort, wo gerade Aktivität war, also schlimmstenfalls, wo er im Leben nicht hingehört.
Das könnte ich noch verschmerzen, auch wenn es nervt. Aber
2. — wieder ohne Warnung/Hinweis! —
• es öffnen sich (alle? zumindest sehr, sehr viele) weitere(n) Inzidienzien dieses Tabs; in meinem Falle waren es zuerst hunderte, weil ich zuerst die dringendste Herausforderung an Privatheit angehen wollte.
Übrigens zunächst mit der (dann ziemlich) dussligen Warnung unter dem Titel “Multi-Account Containers Confirm Navigation”* mit dem Inhalt “Open this site in your assigned container? You asked Firefox to always open CarmaChamleon for this site: (…URL…) Would you still like to open in this current container?
[ ] Remember my decision for this site
[Open in Current Container] [Open in CarmaChamleon]”*.
Und dann noch einer… noch einer… noch… noch…noch… und nochundnochundnochundnochundnoch — und… so weiter.

Das erinnert mich an Windows-Installation im Vergleich zu Mac (früher jedenfalls): Windows fragt jeweils zu verschiedenen Zeitpunkten Dinge ab, statt diese vorab in einem Rutsch zu klären…

Suggestions to the developers:
Please consider those people who — like me — are “tab hoarders”.
—> warn that possibly hundreds of tabs will open when making that choice (at least once, with remember of course), or better
—> find another way of dealing with that situation:
• open in place, why not the same tab anyway? At least in the same window!!! — I (try to) put order into the placing of tabs in different windows, so don't mess with that, please…
• and… well no “and”, that would heal the problem of cluttery and confusion.

In the meantime, address us “tab hoarders” at least by putting up a warning on first usage, better yet a set of instructions — maybe there's a better way to set it up without annoyance and confusion?
Bear in mind, we might have fairly slow computers still in use, so when testing, consider that as well…

Thank you.

And, another thing:
translation.
With German, I offer help. My English is, hm, okay; my German is excellent, I love to use precise expressions that are still easy to understand.

* Übersetzung?!?!? — Deutsch ist nun nicht eine Sprache, die bloß von 20 versprengten Individuen in weit verstreuten Hütten in der Tundra oder dem Regenwald gesprochen wird…!
Ich würde auch dabei helfen, da ich auch Englisch recht gut beherrsche.

I love this extension very much, but after updating, the "Open this site in your assigned container?" appears and I don't know how to disable it.

This page is so annoying and didn't help anything.
