Hello fellow Firefox users, Normally Firefox works wonderfully in Roll20 but a few months ago, I discovered a Firefox plugin that breaks context menus in Roll20: "Video DownloadHelper." I would advise turning the Video Download Helper plugin off before loading Roll20 in Firefox. Leaving it on is the kiss of death to context menus in the application. This is not a bug. I'm only giving this tip out to others in case they have or had the same problem I did.
