Как всегда задумка огонь, реализация для галочки. Нельзя: 1) посмотреть установленные правила в каком контейнере открываются сайты, отредактировать/удалить эти правила без удаления контейнера; 2) очистить конкретный контейнер от куков; 3) добавить свои изображения для контейнеров; 4) сделать так, что бы автоматически создавался контейнер для каждого нового сайта.
На первый взгляд расширение полезное, но когда начинаешь пользоваться... приходит понимание насколько оно не доделано.

Used to be one of my favourite extensions to firefox. But after an update they've started asking whether a particular page should open in a specific container, very often every single time i want to open a page. Just give me an option to never ask for that, ever. If i want something to launch in a particular container, Ill just do it manually.

These are so hard to work with. They sometimes break sites in really obscure ways that are hard to fix. It would be so much better if Firefox had proper support for profiles

They separate single account with multi categories, not multi accounts. They claim that categories exist, but the way to open them is difficult – click here, then here, and choose from there. They may have ideas for the future, but for now, this is my review. Best wishes

A good idea but completely unfinished.

Sync to a new browser always merges the default configuration without asking. The Sync does not sync the 'limit to designated sites' option, so you have to manually apply that to all the categories (while you clean out the merged in default configuration).

Management of the categories is woefully sub-par; how is there no way to manually add domains or wildcard domains to a category? Try keeping a service like Google in a 'limited' category and watch the SSO explode every time you go to maps dot google dot com because the browser doesn't stay on the auth redirect long enough to add it to the container though the UI.

It also breaks the firefox profiler, as the profiler can't load profiles from outside the category.

None of this bothered me when this feature was new, but it's been years. I wish I could recommend this and use it in earnest.

Its good, but half baked. Instead of using profiles, we should be able to isolate history within each container and have default container option. Thats the only basic expectation for this extension

Because I'm used to the grouping feature of Chrome I wanted to give this one a try but this is anything but convenient to use. It's just cumbersome, too many navigations for renaming or adding groups and no toggle feature

hard to change "Open this site with container..."

Great addon and idea, but the sync is a complete sh*t show. When deleting containers, they just somehow reappear, and if likely you'll end up with TWO, since it seems to restore the one you deleted and then pull one from the sync. In short, the Sync feature is completely useless, and have left me with at least 5 duplicates of every container I tried to delete. Can you PLEASE fix this? And there's no way to purge what's stored on the cloud.

Annoying notifications.

I've been testing this extension out for a few weeks and frankly I'm fed up.
The idea is good but it's just not user friendly nor intuitive.

First off it's unclear whether or not every site in the same container can 'talk' to each other. For example: If I open a Shopping container on Amazon, then another Shopping container for Ebay, can the 2 sites share information with each other and profile me?

I tried looking for this question and answer online but came up empty handed. So to be on the safe side one would have to make a separate container for EVERY site they want to keep isolated. That includes separating domains from sub domains.

Second: Sites that I have assigned to containers don't automatically open in said containers. Navigating to the site via the address bar produces a message asking how I want to open the site. Selecting the "Remember my decision for this site" option does nothing, but perhaps that is due to my Firefox settings or other extensions that block cookies and trackers. You would think though that Firefox would make this extension compatible with their built in privacy options.

Third: It takes multiple steps/clicks to remove a site you accidentally add to a container. For me the "Manage Extension" button is cut off (regardless of how zoomed in or not I am) so it took me even longer than others probably to figure it out.

Many people seem to love this extension but frankly there's got to be a better, more hands off approach to stopping sites from tracking and profiling you. If you aren't looking to have every domain and sub domain separate maybe try it, but I will be looking at other options.

Not what I want. I want to be able to have distinct Firefox browser instances with each isolated from the other with its own bookmarks, extensions, settings, etc. The goal is to be able to have one independent browser for work, others for various personal technical projects, others for entertainment, and not have settings and tabs, etc, from any shared between them. Also to be able to have each independent Firefox browser open and running at the same time.
So basically multiple-accounts (browser preferences and everything) contained in independent browser instances.
Other than the benefit of keeping security isolated to each instance the other big gain for me would be de-cluttering, not having and seeing lots of tabs in one browser instance.

This add-on does not achieve either goal; no simple isolation at browser level, and still all that clutter as it is based around tabs.

The UX is horrible. This extension have a design problem with the "No container" state:
* You can move a website to a container, but you can't take it out of a container.
* Moreover you can't choose "no container" as default state for a website if you have chosen a container previously.
* Also the extension always remember your last container for a website and you aren't able to disable that "feature".

Please review the "Cookie Swap" extension, which is much more simple (but it has some bugs unfortunately).

This does not work for me anymore, does not open the urls in the new containers as it should. Something has been broken for a few firefox versions now.

Every time i open a containerized tab, even when doing right click -> open in xyz container it still asks , do you want to open in this container, why ??

4 Days Ago I Installed It. And I Added Facebook And Instagram In Social Media Container. Also I Add Gmail, Google Drive, Youtube In Google Container. Today On 4th Day Of Usage, It Automatically Logs Out From All Websites Like From Facebook, Gmail, Instagram. It Should Keep Logigng Me In On All Logged In Sites. Thats Why Rate It 2 Stars Only. Fix It Please.

It is really good except that whenever I go to somewhere that needs some connection or somehting like google classroom it isn't able to sign in

It is a pity that this plugin does not work on the Android version. It is super necessary.

Works well untill you change computer and set up a new browser. The containers are synced in random order an there is no way to sort them in "Open new tab" menu or in about:preferences#containers tab. There is sorting when clicking on a badge but it doesnt affect order in new tab button. So if you want to have same sorting in 3 different browsers you have to delete everything and create containers one by one constantly syncing and checking all devices. Horrible UX.

I have Firefox 109.0.1.

Firefox Multi-Account Containers 8.1.2 can't open links outside of any container from the personal container if user made 2 confirmations... Links will open inside the personal container instead. It's not clear if there are any hidden settings around this. I don't think that manual requests from the context menu should follow the general rule, they should be given priority. Left clicks and the address bar must obey the rules, but right clicks must take precedence over the rules.

Firefox Multi-Account Containers 8.1.2 will ask for confirmation twice when assigned and then when opening any website.

By default, Firefox Multi-Account Containers 8.1.2 doesn't have even the largest banks...

By default, Firefox Multi-Account Containers 8.1.2 doesn't have even the largest marketplaces and shops. Users have to add shops manually... Definitely not suitable for smaller shops.

It's not clear how to create more than 4 containers or rename the standard ones with Firefox Multi-Account Containers 8.1.2...

It's not clear how to clear some or all containers with Firefox Multi-Account Containers 8.1.2... Users don't have visible options.

It presents a serious problem when starting firefox, it always stays 5 minutes without loading any page when having the container enabled.
