Не работает

My firefox is updated but still unable to add this extension.

Cet add-on indispensable n'est plus maintenu depuis 1 an et est bugué. Par exemple, je dois sans arrêt retirer des sites de la liste des sites gérés par un conteneur car ils reviennent toujours. Ça rend l'identification problématique si un IDP (comme Facebook login ou Google login) se trouve réassocié sans arrêt à un conteneur.

This essential add-on is unmaintained for one year has some anoying bugs. For instance, I'm forced to remove the same website from a container managed website list again an again because it get reassociated again and again.
This cause IDP (like Facebook login or Google login) to fail everytime if their website is reassociated with a specific container. (SSO breaker)

Despite having the "Select a container for each new tab" box checked When you open a new tab, nothing happens. Not even contextual dialogue is activated. I have the extension installed and enabled, but I can't get it to work in Windows 10, not so in Linux Mint, which goes without problems.

no wildcard,no manual edit feature，looping on onedrive.live.com and login.live.com

For years I have *LOVED* my containers. However, a few months ago my containers stopped loading properly. I try to open my gmail in the proper container when I open Firefox (it always opens last tabs) and I have to reopen gmail in my preferred container. If I do not look at that gmail container often enough I have to follow the pop-up to open my gmail in the right container. I tried going to their GitHub for advice and the people were unhelpful and rude. I don't even know how to properly use GitHub! I wanted desperately to fix this issue.

I need my multiple inboxes open all the time. I cannot keep opening them in new containers because their original ones mysteriously stopped working.

이 기능을 설치하면 Firefox 프로스세만 1.9기가, 관련 프로스세까지 합치면 4G에 육박하는 엄청난 메모리 사용량을 보여줍니다. 도저히 사용할 수가 없습니다.

Идея интересная, но почти все сайта разлогинивают при использовании контейнеров.

It's a great idea, but suffers from horrendous UX

This is just TERRIBLE! I don't recommend it to anyone. This extension significantly slows down the browser, works terribly slowly, and takes a long time to load pages. Moreover, it constantly requests permissions from the same site. Save your nerves and look for another solution!!!

Continue to see tabs in containers even after deletion of the extention.

I've given up on this.
There are some great ideas, but the usability is abysmal, development has been basically non-existant for years.

- The extension constantly asks you which container to use even when its the first time you've gone to a website in a specific container or even when you specifically ask it to use a certain container.
- Its also incredibly annoying to try and use the same domain in two containers, in contrast to what the addon claims, because the extensions keeps panicking about which to open and tends to override your current container choice at will.
- Its impossible to migrate your addon config to another profile or device, only the container names can be backed up.

I've used it for years and have found it to be more trouble than its worth. Rather than having a simple all-in-one profile swapper it is more akin to just colored tabs that break websites, make it impossible to use the same domain in multiple containers without hassle and doesn't respect your explicit choice of container half the time.
