Cool extension for accounts segregation. But lacks following:
- open URL in previously selected container without asking if I selected "Always open in ";
- open URL containing subdomain in container if I configured that container for main domain (example: shop.com, hardware.shop.com).

The only features I would like to see in this add-on to give it 5 stars:
- the ability to re-open tab in a specified container
- the option to have the sessions associated with add-ons be global or have the sessions be different for each container

The always open this site using a container feature is very helpful. If only there's an easier way to open the current page in another container instead of having to open a new container tab and copy paste the url.

That exclusive Facebook Tab helps you maintain your privacy.

Just what I need. It will be really good if the colors are customisable, I found the provided colors are too bright and distracting.

Very usefull when combine with Containers Sync. I hope it will have option to re-posittion Containers in the future. Thank you.

I really like the extension. It would be very helpful if one could synchronize the containers via "firefox sync".

Edit:

I have managed to "sync" the container settings manuel. I installed Linux and wanted to use the same containers as before with Microsoft. For this you only have to copy two files:

1. "containers.json" (Microsoft: user - AppData - Roaming - Mozilla - Firefox - Profiles - xxxxxxxx.default)
2. The "storage.js" File from @testpilot-containers (Microsoft: user - AppData - Roaming - Mozilla - Firefox - Profiles - xxxxxxxx.default - browser-extension-data)

Close Firefox, copy and replace both files and restart Firefox. This worked for me.

I enjoyed being able to easily separate my work tabs from the tabs I have open during break. Being able to show/hide all tabs in a container is an awesome feature too. Just wish it was easier to access.

It's very useful to be able to keep my accounts separate, both from a business perspective (multiple google/microsoft accounts), as from a privacy perspective (all google or facebook tabs in their own containers). It may be a bit of a hassle to set up, especially since you have to set it up separately on each device. Once it's set up, it works really well, always opening websites in their assigned containers. I would like to see a sync feature, and the ability to reload the current tab in a different container.

Super extension, permet d'ouvrir plusieurs comptes différents dans différents onglets. Ca serait bien de pouvoir définir une URL à ouvrir automatiquement quand on ouvre un container

Great, only separate bookmark handling is missing ;)

es genial, me ha servido de mucho :3

[es] Funciona muy bien y el concepto/idea es muy útil; usas un container para ver productos y eso impide que tu navegación en los otros se llenen de publicidad basura. Además puedes separar cuentas. En fin, contextualizas tu navegación. Sólo le falta un acceso rápido por teclado para abrir los contenedores.

[en] It works very well and the concept/idea is very useful; you use a container to view products and that prevents your navigation in the others from being filled with junk advertising. Plus you can separate accounts. Anyway, you contextualize your navigation. It only needs quick keyboard access to open the containers.

Its awesome

Bitte ermöglicht das Syncen der Container via Cloud! Muss jedes mal neu alle einrichten :(

always great to separate cache & cookies

とりあえず、入れておけば他のブラウザやFirefox自体のプロファイルの使い分けを減らせるので便利です。
欲を言うと、次のような機能があったらいいなと思います。
・メニュー上のコンテナを任意の順序に並び替え
・ステータスバーから新規タブを開く際のコンテナ選択をするかしないかの設定
・タブやページの標準コンテキストメニューでコンテナの移動やコンテナ別新規タブのオープン

更に欲を言うと、タブリストボードのようなタブの一覧をグループ化して表示するアドオンやセッションマネージャーと一体化し、一覧ページ内でコンテナ別に表示して、まとめてブックマーク、まとめて閉じる、以前開いていたタブをセッション付きで復元と言った操作を簡単に行えたら最高ですね。

Fairly good, and certainly an improvement over one of the few features that kept me on Chromium/Chrome until now. Being able to sand box tabs is quite useful for the sites (social media) where I have multiple accounts, now I needn't log out/log in to use them, and it even helps with sharing.

Hopefully we'll see improvements in the future, I for one would like to see more control over the default container, and would like an easier way to select the container than the current button/list (ctrl+c1/ctrl+c2 perhaps?).

EDIT 3 NOV
Still liking this, but seeing one area that could use to be improved, it'd prolly be a good thing if the highlights section of a new tab was restricted to content previously seen in that container.

I really appreciate this extension! However, some essential features I am missing include:
* Ability to sync settings. I've recently found myself having to delete and recreate profiles to no end, troubleshooting an issue with another extension. Reassigning my banking sites to the banking container, my email to personal, etc., etc. is fun the first time, tedious the 3rd, and frustrating past that.
* Ability to automatically open a site in another container. For example, I forget to FIRST select that I want a certain container, I just go to the site. Oops. Now I have to open the correct container, then go copy the URL and paste it in. Would be great if we could right-click and "reopen" in or "move" to a different container.

I'm certain I gave feedback on the first one some time ago somewhere, but can't find where that was to follow up. (email? Twitter?) I'm finding myself about to recreate a FF profile again, and even just being able to save my current settings and then manually reapply them would be a good workaround at this point...
