The only thing that is fundamental and that is missing now in Firefox is ability to show only one container at a time. Similar to Tab grouping that has been disfunctional from FF57. Power Tabs is nice add-on for newer versions but it's that's much bugged it can't be used.

Very handy and useful to log in with your different accounts (professional, social media etc...)

Does exactly what I need it to--keep logins for multiple "personas" using the same services separated. This is a huge time saver!

Simple et facile. Un must have !

Very useful for multiple logins and for keeping trackers under control and preventing them collecting your entire online world! Would be nice to have the option of syncing settings via Firefox Sync though if you wanted to use that.

Si vous tenez à votre vie privée c'est l'application idéale au quotidien.

It's a nice way to categorise my tabs without using multiple accounts. I just wish it could sync your settings across installs.

Luar biasa, lebih dari Incognito

More flexible than the Facebook Container and similar extensions. Easy to set default containers for various sites, which will keep them contained. You can also revisit some news site inside the Facebook Container to be able to use the embedded comments functions if so desired. I still recommend Facebook Container for basic users, but this extension gives you more control and customization options. Well done!

Works exactly as intended! It functions seamlessly within Firefox, and it was quite intuitive and easy to set up exactly how I wanted it. It also works flawlessly with other add-ons I use like "temporary containers" and "cookie auto delete."

Great add-on. Much more flexible than switching profiles. My wish list is to be able to assign a default container per window.

This works really great. I just have one bug to report. If a container is hidden, and I choose to move tabs to a new window. The tabs open in a new window but each of the tabs are duplicated once. It's a bit annoying but surely fixable.

Do his job properly and unintrusively

I find container tabs separate my online activities pretty well and make me worry less about my privacy and security online. I think this is a great feature, one of those that keeps me coming back to Firefox.

This does exactly as it describes. It's fairly easy to open or create new containers. That said, I would like to see a few changes to make it even easier to use.

Right now, when you create a container, that's all you can do on that screen. You can add permanent sites to the containers. You must open the site in the container, then check a box. In one way, this does prevent any errors due to mistyping, but it would be handy if it could search my history or bookmarks and find sites to add as permanently in the container.

It would also be great if there was a "containerize this site" button. Essentially, use the current site as a sample to make a new container and permanent rule.

Additionally, it would be helpful if pre-configured lists (e.g. all social media sites) that could simply be imported for this purpose.

Excellent concept, and works great. I just wish there were some (programmable) hotkeys for opening and closing tabs for containers.

Es una excelente ayuda, especialmente para quienes desarrollamos y necesitamos diferentes sesiones, cada una limpia de cookies, y probar al mismo tiempo con diferentes usuarios.

Always use it whenever i need to use multiple account for the application in am developing.. By opening multiple accounts and testing between tabs..

Please add "Responsive Debug Panel" for these containers too

Love this add-on. It should be built in (currently there is a builtin one but that is limited at what it can do).
4 missing features will make this add-on as close to perfect as it can get.

1. Restricted container so that ONLY the sites specified to open in a container opens in that container. All other sites open in default container. For example - When this setting is on, clicking a link in a container should open the new site in the default container (or its own container if there is any) instead of opening in current container. So clicking a non facebook/google link in a container specified for Facebook/Google will open in the default container.
2. Backup/Sync containers so that when Firefox Sync is in use all containers and settings will automatically propagate to all instances of Firefox in use.
3. Ability to move a currently opened tab into a container.
4. (Too far-fetched) Container for Firefox iOS/Android.
