Hi there, so now a days in the company that I work, there are multiple accounts of the same website, like microsoft or whatever, which is a pain to deal and usually I went using multiple browsers. For each browser I usually setup the initial pages to be the 3 main used ones like mail + chat + files. Recently I found out about Firefox multiple-account containers, which is super nice to have all those accounts open at the same time in just one browser with different sessions on each container. The question is, is it possible to have the startup of firefox, to open multiple tabs in different containers? So, when I open firefox, it opens all main tabs for all containers I saw that you can have multiple start page with "|" symbol, but that does not play nice together with the containers. If anyone has a tip on how to make this happen (multiple extensions or changing some config file) that would be very useful.
