As a player in a play by post game, 80% of the game is played on Discord, the rest on R20. Last night, when opening an instance of Roll20, it crashed my Firefox browser. This caused me to have to sign in to R20 multiple times. Today, upon signing in, Roll20 crashed my browser once again and upon opening it again I found that not only had the browser crashed but it had done so in such a way that it signed me out of all active sign ins within Firefox.
