Multiple instances of Roll20 on same computer

I had a question about multiple logins on the same computer. The situation I have is that one of my players moved to a different city. The rest of the players are still here. Would I be able to run the GM window from my computer and let the 4 players that are here run off of one laptop? Could they each open/login on a new window and just switch to their window when it's their turn?

Yes, though if any of them refresh, they will get the last one to login's version.

Better would be to take advantage of Chrome's multiple users. You go into the settings and click Add new user..., adding an entry for each player. You will then have an icon in the upper right corner which you can click to select the user you want. Selecting a user opens a new instance of the browser with it's own configuration and cookies, etc. I use this at work for keeping separate accounts logged in for my personal and business sites. At home I use it for my different kids as well as keeping my Roll20 sessions separate for testing API scripts, etc. I suggest setting a different theme for each user as well as a different icon.

Never thought of that. Thanks! :)
