I use Chrome, mostly because I typically armchair-use Roll20 from a Chromebook, although I run and play on a Mac. I have used Firefox in the deep past, whenever it seemed to have leap-frogged Chrome in performance. I have not had any game-affecting Chrome issues in years, though, so Firefox is mostly used for testing. The real and true answer for which browser to use, though, is whichever one works best for you . "Supported" just means that if a browser update breaks Roll20, then Roll20 commitment is to update the code to account for it. Browsers all have little bits and pieces that work differently, and are constantly under development. To make something like Roll20 work requires leveraging a lot of different services and technologies. This gets harder and harder to do as you multiply browsers. Back when Roll20 first decided on these two, they were pretty much tied for user base, after Internet Explorer, and the writing was already on the wall for that old software. Nowadays, Chrome is head and shoulders above all other installs, across platforms and devices. I'm kind of surprised that firefox is still supported, since it has less installs than even Safari (which is artificially inflated due to mobile installs). I have had players use Edge, for instance, when it worked better for them. Another I think used Brave. Out of curiosity, what about Roll20 is broken on Opera? Just generally poor performance, or does something actually not even work?
