This add-on is pretty great but there are time when it completely removes all my data and I have to basically re-start and re-setup all my containers and say which sites open up where for no reason.
Just happened tonight where my three pinned tabs were all of sudden closed (about 20 seconds after just freshly opening the browser) and my custom containers don't exist anymore.
Could be my own issue where I use Firefox Nightly during the day and sync with Firefox Beta in the evenings so the sync-ing process messes things up but I don't know.
Makes me sad.

would be nicer if you had 2 more options:

1) option to enable/disable "Sort Tabs by Container" within settings with a checkbox or move it somewhere else, where you can't click it by accident. It's more than annoying if around 600 tabs get rearranged when you had them in a specific order …

2) an option to force the current container to inherit and thus override the settings for target tabs during this session only. Use case: online shops have their own container, banks have their own container, thus you can't really pay in an online shop as it switches to bank container and thus loses all important cookies and payment information. Add a tick next to url bar for override during this session and bank and all subsequent redirects would thus get the online shop container but ONLY during this session.

Very good extension for when you have multiple Microsoft accounts. One problem: everytime I sync my containers on a new device it adds the default containers, I have to remove them one at a time.
Ideally, it would be nice to delete the defaults when I sync; at least it would be nice to have the possibility to delete multiple containers at once.

Missing export/import capacity.

Honestly unclear how to use this ext properly. Seems as though Mozilla VPN client (stand-a-lone app) must be turned on in order for containers to fully function as expected (that is the VPN client I'm using). But the VPN app already encrypts all traffic. If this ext is just to segregate tabs for quick access and set specific endpoints then great job Mozilla. I was more interested in having the web traffic routed through VPN without needing to have the VPN client active. Like if you are gaming on one screen while shopping on another, esp. if the game requires Anti-cheat, having the VPN enabled doesn't work. Maybe its just my understanding of what this is intended for...? pssst... new feature Mozilla :). In any case it works great for keeping tabs organized into buckets, as well as setting individual VPN endpoints for each.

CPU Per% is very high想请教一下这个功能和edge自带的多用户配置的区别是是什么？

Please be aware that version 8.0.5 broke the Proxy per container settings!

Works properly but it would be a lot better if it allowed me to automatically assign a container based on the full URL regex instead of the domain name only.

The problem is: I use some sites for both personal and work purposes. One of such sites is GitHub. All repos are hosted under the same domain name github.com, and the repo is selected by the URL path.

This addon can only assign all those repos automatically to one container. Which then poses a problem when e.g. I click a link to a work-related repo and it automatically opens it in my personal container and I obviously can't login. So I have to force a different container manually and it is annoying.

This extension works more or less as expected, with one minor gripe.

I have reddit set to always open in a container, but I don't always want links opened from it to open in the same container.

I want to be able to click the type of container it's in and remove it, without having to copy the url and open the site in a new tab. Ideally this would pretend to be a self-referring link.

Should this functionality be added, I will adjust my rating to 5 stars.

I'm using the containers mainly to separate business and private browsing. Works smooth and effortless.

One of the best addons for today's internet.

Almost perfect. We just need a way to open sites in containers specified directly using Firefox command line options or with custom URLs.

E.g. Having a Windows shortcut that will open a site in one container and another shortcut that will open it in a different one.

This is unintentionally a very good tool for systems and there doesn't seem to be any real limits to how many accounts you can have. The only issue we've run into is the limit of tab colors can make things confusing, and I can't see why there isn't a custom color option unless I'm just not seeing it.

The idea of having separate containers for different online activities is great, but it's annoying when you create new containers and they disappear when you change something on the settings and the fact that you can't import your stored data into the containers unless you do it manually...

Has done what it's supposed to do so far. A caveat though: when I've set a site to open in a container, I can't revert that change to it to open without a container/in a default one.

I like idea that Mozilla tries to move some of the power user functionalities into add-ons making the browser more lightweight by default.

But I really missed this feature, when it was removed and just found this add-on today.

Isolation of trackers, always a good thing! Would be 5* if it were possible to manage the stored data for a particular group of containers, Shopping, News, Google, etc.
A news site that downloads 50 or more, highly intrusive and persistent cookies and trackers will need "cleaning" far more than my "Work" tabs that are typically Linux and FOSS technology which (in the main) seem to use minimal cookies.
