Is it possible to install multiple versions of Firefox on the same computer? Here's my problem: I'm a social media agency managing many different businesses platforms. Because of this, for sites like Pinterest, it's a pain to have to log out and log in every time I need to do a different clients Pinterest platform. Currently my solution has been to install different browsers like Safari, IE, Chrome, etc.. but as my business grows, I'm running out of browsers to install. I read other threads that say to just custom install it in a different place, but that didn't work for me because the cookies remained the same. Any ideas on a solution?
