amazing tool to contain sites like google and youtube

Gives the ultimate freedom to use multiple accounts.

Pretty handy. But the icon in the URL bar is pretty annoying, as these cant be removed. It is not nessecary, but when tiling the FF window in half the URL bar is nearly completely gone, which is not nice.

Permet de compartimenter certains sites dans des containers différents ( par ex. finances, paiements en lignes, réseaux sociaux ... ) étanches entre eux : un pas de plus dans la sécurité

very useful

Highly recommend this - great for managing multiple accounts (e.g. mail)
