Mozilla’s Multi-Account Containers splits Firefox into colour-coded cookie jars. Campus Gmail in the green container, personal shopping in another, the student LMS in a third. They do not leak login state into each other.
Firefox only. Free. This is the main student reason to keep Firefox around even if Chrome is the daily driver: campus accounts stop taking over every Google tab.
