I personally like Firefox and this was the one feature it was missing for me to use it. After using it for a bit it was incredibly annoying to NOT have the current container open when I use Ctrl+T to open a new tab. Every time I open a new tab instead of it being a one step process It's a five step process. This makes me think that this program wasn't tested by anyone or was coded by monkeys. It's not even an option that can be changed or modified within the settings. I really want to use Firefox but until they change this I have to continue to use Chrome.
