Essential plugin as long as profile switching is a bit cumbersome i Firefox

Would be nice to be able to a specific container to bookmarks since it's only possible to pin domains to containers, which means that services like azure devops that relies on the url for deciding which account you're trying to go to cannot be automatically opened in a certain container.

dev.azure.com/company1
dev.azure.com/company2

This add-on is really, just one thing is missing for me, the ability to add rules like "'*.example.com' must be in work container", you have to whitelist every subsite, that you want to open in the same category

It's a nice sense of security knowing that different parts of my browsing stay contained and there aren't cookies tracking me everywhere.

I'd give 5 stars if we could easily edit and share lists of sites pinned to each container, rather than having to visit each one first and then set it to always open. It would be great to download a long list of shopping sites and have them automatically relegated to the shipping container.

Very useful for privacy and multiple accounts on the same service. I only wish the containers and settings would sync through Firefox to other browsers. It's a big pain to add them by hand to multiple computers.

The concept is great and execution has come a long way to make it a generic version of "Facebook Container" addon. A nice way to set and manage user preferences is needed, though.

I really like this extension. It's potentially a much better solution to the "I want to keep my work and personal lives separate" problem than other browsers (see profiles in Chrome). I hope the interface for setting default tabs for domains becomes a bit more robust, and that the interface improves for opening existing tabs in specific containers. I know these are under discussion so I'm optimistic. :)

Please, please, PLEASE allow us to backup and restore settings with Firefox Sync. Batch categorization of sites in the bookmarks manager without the subsequent "Open this site in your assigned container?" notification would be great as well. This will be the best extension ever if you can get these two things done!

This is a great extension for separating work more effectively across multiple accounts on the web, all for different purposes. You can choose to create your own containers if the default options are not enough. I would like to see an option to add custom Favicons for each container, and RGB color choice for the default colorful icons. The most important change I would like to see is that when I set a website to open in a container by default, I should be able to reopen that site in another container without it defaulting back to the choice I made. Keep up the good work.

Decent enough duplication of something that is REALLY simple on Google Chrome, which I finally abandoned, but I wish it were more user friendly. And I REALLY miss the different bookmarks toolbar I was able to use on Chrome! Works though and it's a good idea. A tad better implementation for us nongeeks, please.

i hope profile can be save,

I love this addon and I use it everyday, but it is frustrating to see that it gets no love from Mozilla. There are so many improvements that could make this a far better version of Chrome tab groups, but it does not get the features that would unleash its real potential (just check Firefxof ideas).

Fonctionne très bien.
Pas d'enregistrement / restauration des paramètres pour passer à un autre ordi ou si restauration de Firefox.

Terrific add-on, lets me log into multiple accounts and keep several identities on websites, would love if it came with every installation of Firefox as its just that useful. Only needs a option to clear data/cookies for each instance.

Honestly, this is something I didn't know I needed until I decided to try it out. Lets me easily see what kind of Firefox browsing window I have open, whether it's mostly an entertainment window or just a random browsing window. Essential for someone that likes to have multiple browsing windows.
Though it is a great add-on, it could really use more symbols and colors. I find I struggle with categorizing entertainment-type tabs. Overall, great.

It does exactly what I wanted, but working with it is so cumbersome. It requires too many clicks for simple operations, like opening a tab in a specific container, or switching containers. I think having windows that will open by default the selected container would speed up my workflow. It should also come up on more contextual menus, and definitely showing your options directly, and not as a submenu. It works flawless and it allowed me to ditch Chrome, which is what I wanted, but the UX is not as good. I am looking forward to seeing this extensions as part of the stock browser having a much better integration.

add proxy each container,
add canvas fingerprint different or random each container,
add user agent different or random each container,
sync to firefox acc or local file backup

will be perfect!!!!!
