Yes. 100%. When I'm browsing the internet I don't log into anything. Mullvad browser is perfect for that. On Mac and Linux this is very easy to do. You can set it as your default browser.
On Windows you have to go through some hoops to set mullvad that as your default browser, but I'm sure the team is going to come out with an official solution
If there's something going to be logging into recurrently then I use un Google to Chrome and make a specific profile for that sit
