Hi there, folks. We’ve been working on a fix for Firefox v. 52/56. The patch has been written and is currently in testing. Since it’s been quite some time since these versions were supported, it’s been a little bit more complicated – and taken a lot more time – to develop this fix.
A fix has been made for Firefox v. 60. If you are able to, please check for an updated dot release, which should address the issue. If you are at a company where an IT department manages which version you are on, please kindly ask them to deploy the updated version 60.
