As Rabulias says, Roll20 only supports those two browsers. However, it is worth trying to work through our guide to Solving Technical Issues . Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. (Though this will likely fix your issue, this isn't what you're testing) Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please seriously consider moving to a supported browser so you can enjoy the full Roll20 experience :) Thank you!
