Due to the Sars-cov-2, I was forced to start creating several accounts for the same websites (such as G-mail) to communicate with my colleagues, students, teachers, and classmates, and it was a pain in the **s. I started using several browsers at the same time (with their Private Navigation) to use all my accounts without mixing things or having restrictions from the platforms. And then, I discovered containers, it is the holy grail, needless to say, I can use all my accounts separately in my favorite browser and it has been truly a relief and super helpful.
