This is a great idea, as are containers generally: isolation much like virtual machines, but a level higher (above OS) so with much less overhead.

This particular app works well but is frustrating in one respect: you cannot specify to open a site in container X in future without already having done so. As it is, you must first re-open your site in a preferred container, then choose to always do so as a second (manual) step.

Even so, this app provides cross-site isolation. I feel much better having all my banking in a container no other apps see.

I accept Facebook tracking my tastes & movements as a fair exchange. If you don't, use the Facebook Container app but get this one anyway, for everything else.

Seems to have broken after recent update. Can't open Google Voice in a container anymore. Get "The page isn’t redirecting properly"

Sometimes "Always open in {container}" doesn't respond. It seems like "Always open in Default" never works.

Excelente para no mezclar trabajo con cosas personales

Indespensible add-on!

Working fine like I expected. Favorite one.

If I'm in a Google container and I launch a site that isn't attached to a container it should open in Default, rather than google. I kept wondering why I had to reauthenticate sights that weren't attached to a specific container. This is really interrupting my workflow. Other than this I have no complaints. Okay, new complaint: really need a method of exporting configuration.

Coming from Chrome, where I used profiles to separate work browsing from personal browsing, I find this very useful.

I really like this add-on. It would be perfect if we had the option to 'lock-down' a container of choice, in the same way that Facebook Container is locked-down.

Works great, but sometimes I forget that when I log in on a Google account for a different website I need to open my separate tab.

Great idea, lazy execution.
Often fails to contain certain sites in their containers, popup for confirming a site be exclusively handled in given container sometimes unusable. Containers are a single flat list.
All that is minor, for an official addon it cannot sync settings, and settings are partially lost when disabled. Sites contained in default containers will be remembered, custom containers permanently lost.
If you are going to delete everything on disable (not remove), for any reason, at-least be thorough.

TLDR: Bare minimum functionality, still buggy. Is being an example an excuse for being poorly done?

Di base è ottima ma è troppo limitata. Oggi ho perso tutte le preferenze e non posso recuperarle. Per favore aggiungete il backup, inoltre non è possibile selezionare da menu i siti salvati, dovete creare una UI decisamente più completa e che permetta di personalizzare i domini aggiunti.

I would love to see some sort of way to save my preferences about which sites open in what custom containers, e.g. save it yo my firefox sync account, or save to a simple text file, or to some cloud storage or in whichever way that seems most applicable for this sort of data

Easy and straightforward way to keep different browser contexts separate.
