> I type "gmail work", hit return and Firefox opens it in the correct container tab, already logged in. (Honestly, who uses bookmarks any more? They just turn into a bloated to-do list, hundreds of links you'll forget about until one day you try them and the domain no longer exists)

Do you just have a google container, or have you managed to make it so that gmail can only be opened in a "personal" and "work" context and bookmarks open it in the right tab? That's been my big frustration with using container tabs to seperate purposes/accounts like this.
