If you’re running Chrome on Ubuntu (likely elsewhere too), you can run multiple copies of Chrome with fully different profiles by launching it with the --user-data-dir option. For example, I run two copies of Chrome like so:
/opt/google/chrome/google-chrome --user-data-dir=~/.config/google-chrome-work &
/opt/google/chrome/google-chrome --user-data-dir=~/.config/google-chrome-personal &
