Does what it says on the tin, and it does it as well as I could possibly ask for. A little bit of work is needed at the start to set up your containers, but if you just set up containers for the stuff you'll be doing on a regular basis ahead of a time you won't run into much if any headache down the line.

Bonjour,
A l'heure du pour vivre mieux restons cachés, addons très intéressant.
je l'expérimente actuellement, peut-être mal, la synchro, entre machines, de configuration des conteneurs
n'est pas stable. Sur ces deux machines l'option synchro étant cochée les onglets perdent ou trouvent modifiés leur affectation conteneur...Sur les deux PC

Merci pour le job !

Great app. Super useful app for keeping your various web browsing in different containers. I hope this addon gets built into Firefox one day.

IMHO: Some of the options and menus need to be improved / streamlined before it gets added to Firefox. It is too easy to setup "always open in a specific container" and then later you are annoying why you cant open link in a specific container.

Very useful and productive tools so no need open a lot of browser. Kudos to team Mozilla. Waiting for another useful breakthrough.

- disabling and re-enabling the plugins deletes the complete config
- every now and then the extensions asks where to open an URL although it is already configured

Great idea. In the end it does something a browser should do naturally.

Wekt top, alleen zou het super zijn om ook containers aan bladwijzers toe te voegen. Dan kan ik bijvoorbeeld mijn Microsoft accounts goed gescheiden houden. Ik heb dit nu voor elkaar gekregen met een Add-on, maar zou fijn zijn als dit native werkt.)

Perfect to using multiple AWS accounts and isolate some sites. with this features below, it could even be better:
- Not only automatically isolate sites by domain, but also by path, this way we can give it different site permissions or better manage more complex sites (example, for different logins or different features)
- support setting a bookmarks to a specific container, to avoid having to manually manage that
- much more icons and probably also more colors
- move tab to a (new) container, open a question windows, allowing it to remove cookies, storage, history from main account and choose if a existent container or create a new one. Doing this manually is a pain

This could make this perfect... but still, as it is now, is still VERY good, totally recommended

Very helpful tool that helps me to check different user scenarios in a service while development process. No need to open private tabs every time.

Honestly, it did EXACTLY what I wanted it to - allowed me to sign into multiple accounts in one browser at the same time. I play a lot of different games, and it's nice to be able to easily access my alts!

1. No ability to separate site list by a part of URL, for example google.com vs google.com/maps.
2. Leaves a phantom open tab when using a custom new tab page extension every time you open a new tab, if your search engine website is in a container and tab behaviour is not set to "replace".
3. History is not shared between containers if tab behaviour is set to "replace". So I need to press "Reopen closed tab" if I want to go back? Not the best UX.
4. Desperately needs "create a new container for this website" feature.
5. Needs more colors and icons.
6. Firefox settings menu has a separate Container Tabs setting, which has a different set of options compared to this extension. For example it has an additional color set, which will appear as black in the extension list. Very confusing which ones are which.
7. Numerous bugs like being unable to open a page in "No container" if that website is already assigned to a container etc.
