Hi Vitor. While Roll20 will work in a variety of browsers, in order to maximize your playing experience and take advantage of everything that Roll20 can do, you should use the latest version of either Google Chrome or Mozilla Firefox . Wiki docs, <a href="https://wiki.roll20.net/Solving_Technical_Issues#S" rel="nofollow">https://wiki.roll20.net/Solving_Technical_Issues#S</a>... I understand not really wanting to download Chrome. Would you be able to try Firefox? Those are the only 2 browsers that are officially supported for this. Perhaps other members of the Community will come to reply with other workarounds, solutions or experiences with this.
