Hi there, I've been a fan of the multi-container feature for quite some time, and I enjoyed it most of the time. The only thing that annoys me, however, is that eveytime after I've removed some default container named in Chinese(I'm a Chinese and my Firefox UI is in Chinese as well), Firefox always added those same container back! Everytime! I just want to keep the containers that I've named in English and nothing else, and yet Firefox doesn't seem to understand that. It seems Firefox thinks I, as a Chinese, would definitely want those containers named in Chinese, which I don't. Hope you understand, and someone from the dev team can help fix this, because other than this specific issue, I don't have any complaint about Firefox, which is just a great browser and is keeping get better and better! Thanks and have a great day.
