My checking account is in a banking container and opens fine. The credit reporting service they use would not open in the same container. The link would open in a new tab. Couldn't find another way to give this feedback.

When using youtube I need to restart the browser frequently because I get false "offline errors":

Connect to the internet
You're offline. Check your connection.

Deactivating the plugin after getting the error doesn't help. You need to restart firefox. Really annoying!!!

While substantially improved from previous versions, this is still a broken extension. Since sites can only be added by visiting them, you are prevented from adding some sites which use multiple automatic redirections in their login process. Other addons like Containerise or Sideberry handle this without issue. The inclusion of nagging about Mozilla VPN makes this the most commercial of all container addons.

Previous versions were much worse; opening the site list for a container actually allowed all sites on that list to place cookies in the current container, this bug has been fixed and the default containers in containers.json (Personal, Work, Banking, Shopping) no longer have tracking IDs. Before this was fixed, this addon was a net negative for privacy.

It was super, but now everytime asks where open a link.
And "Remember this decision" does not work.
The only way I found to remove is this:

Is it any shortcut for fast sort tabs by container? The sync it spam my containers

Normally this would be 5 stars, but some updates ago they removed the "Always open in No Container" option. I keep getting annoying pop-ups when opening pages that I wrongly set to open on a specific container and I am unable to change it.


Please fix this!

The "Open this site in your assigned container?" page is so annoying. I would prefer to be able to choose a default container inside and choose specifically which website I want to open on a specific container.

It breaks sites when placed in a container and I am unable to remove them from a placed container. Consequently leaving the site inside a container without being able to revert it back to a normal tab. Even trying to open it as a normal tab does not work since it only reopens it in the same placed container tab.

Good idea, annoying execution. Developers need to spend more time actually using it. When a URL is assigned to a container and that shortcut is selected, the assigned container opens up like it is supposed to. There is a blank tab on the browser. Lots of clicking around to use it.

Also, my low rating is because I had been accessing my bank and things through a banking tab, but that suddenly stopped working. The browser is fine, I shut off this extension and was able to connect just like I can on Brave.

Review was great for quickly sqitching between accounts for websites, no signing out then in again to spend a few seconds to see if something had changed. Unfortunately Firefox crashed. Not an issue with any other extension, but with this EVERY account was nuked and the settings were reset to default. No way to import/export, no backups, I have to manually re-create everything.

No ability to turn off color indicators on tabs. I know addon is working, I don't need to see a rainbow when I have a lot of tabs open. It clutters the inteface, makes it look ugly and makes it less obvious which tab is open. Also no temporary containers functionality so you have to use it with cookie auto delete for the full experience or just use temp containers addon which is much better option.

After the latest Firefox update, CONTAINERS color settings is very poorly visible, it is impossible to understand what container is the open tab, correctly please!
Add various options for the location of the color label to select the user.

После последнего обновления firefox очень плохо видно цветовые настройки контейнеров, невозможно понять в каком контейнере открыта та или иная вкладка, исправьте пожалуйста!
Добавьте различные варианты расположения цветовой метки, на выбор пользователя.

The functionalities are great. Unfortunately since Firefox 89 was released, this addon started causing huge CPU spikes on my system, making UI interactions very sluggish. Unusable right now.

Sehr hilfreiches Add-On aber eine Kleinigkeit die ich fast schon als bug bezeichnen würde nervt mich. Wenn ich auf einer Seite bin die einem Container zugewiesen ist und dann im gleichen Tab auf eine neue Seite navigiere die keinem Container zugewiesen ist, dann wird die neue Seite im selben Container geöffnet was ja das ganze Konzept zunichte macht. Die Seite im Container soll ja grade nicht wissen wo ich noch so unterwegs bin im Internet. Ich nutze die Extension erstmal weiter und hoffe dass das bald behoben wird.

actually it's useless in cloud. i can't open spotify in container in any other device when it's saying there's cloud sync.

打开多个容器标签后，CPU和硬盘使用率会升高，CPU会占用50%，硬盘会一直有20Mb/s的写入，但并不会占用实际空间。

Can't login to Google when limiting www.google.com to designated sites.

Addendum 2: So, I got a new computer and I used this extensions sync feature. Regrettably, in the process of doing so my site lists for my containers were nuked. This has caused more headache for me than the privacy benefits are worth.

I'm finally uninstalling this extension.

Addendum: I didn't realize briefly turning this extension off would wipe out all my containers and settings for this extension. I turned it off for a bit since my Dad might need to use my browser for a bit and I didn't want him to be hassled by my extensions. So, I wish there had been a warning about this or a way to backup my containers and settings I've created over the past few months.

Original Review: Something I never knew I needed. Lots of user-friendly options such as being able to set a website to only ever be opened in one container. This means I don't have to first open a tab in that specific container then go to that website. Also, it's handy in preventing every social media in existence from tracking me since I've put each of them in their own container. Thank you Mozilla!

The concept of this extension is a good one, except this extension does not play well with other extension and cause FF to freeze and even lock up your PC

I would not count on this to do what it claims. Facebook is VERY aggressive in deleting accounts of people who try to modify user experience on FB. You risk losing your account with this add-on.

Ne fonctionne pas correctement. Ne récupère pas les contextes existants. Une fois le module désactivé et réactivé, les contextes ont disparus.

in firefox windows 10x64, the default home tab, i am unable to assign container. why?
