ScoutForce works in all internet browsers, but there are a few that we recommend. We highly recommend Google Chrome and Firefox. Safari works fine as well, but we've noticed less issues with Google Chrome and Firefox. We would recommend not using Internet Explorer because for some reason it just gives us issues. Also, to make sure you are taking advantage of all the latest features ScoutForce has to offer, be sure that no matter what browser you are using, you have the latest, most up-to-date version of it.
