I really love this add-on! I recommend using "Containers Theme" add-on together with this add-on so you'll know exactly which container you're on without needing to look at the address bar ;).

I would like to suggest a few things:

1) There should be more colours in the selection. Better yet, we should have a colour panel to choose our own custom colour for container tabs.

2) Is there a way to add more icons into this add-on? It would be awesome to have a wide variety of icons to choose from in addition to the preinstalled ones.

Great app, easy to use though occasionally a bit clunky. However,
-1 star because I can't save tabs and containers, just tabs. So if I save facebook, but have a personal and business account in two separate containers, it will reopen a single facebook tab. Please add this feature
-1 start because wildcard urls aren't supported (e.g. www.*.example.com and www.example.com/*)

This extension gives me a measure of control over the way my data is spread across the internet. It feels like the first meaningful innovation in browser technology since... the idea of tabs.

Ottima idea così i tracker di certi siti non possono andare a curiosare gli affari tuoi!!

BUG: Since Firefox Update 75, there is a bug. When opening a website that was assigned to Container A, while being in another container B currently, it asks me if I want to open it in the current container B or in the usual container A. It doesnt ask anymore, it force opens always in the usual assigned container A. This makes no sense, because it makes more sense when I am able to open it in multiple containers, especially multiple email accounts from one single provider and such. Pls fix? :(

Cada vez más uso los contenedores, y cuanto más los uso más problemas tengo.
Se empecina en mantener vinculado un url a un contenedor y no hay manera de desvincularlo, lo que produce muchos errores y pérdidas de tiempo.

This plus the related Facebook container have made browsing much less complicated!

Overall this is a great add-on, but it would be even better if I could specify links to default open in no container. That way I can have, for example, news.google.com open in a google container, but links to the news sites open in no container.

La aplicación es muy fácil de usar. Puedes personalizar cada contenedor y cumple perfectamente con su objetivo. Es genial
