As you can see from the table, Google Chrome consumes the least amount of memory. For the author, this is the best browser of all in terms of convenience and other parameters.
Opera, as noted by BogdanKolodii, is the slowest option. As for Yandex.Browser, it is not equipped with the most convenient and intuitive interface. But the Mozilla Firefox browser turned out to be extremely fast and convenient, but it uses a lot of RAM.
