Dear Devs, This is not really helpful at all, as whatever the intention was, the easy solution was to install google-chrome, which is hardly a solution at all.
Whether we like it or not, many things we need are neither free nor open source, and this compilation means one must either use google- chrome, a truly commercial mess, change the environmental variable, or give up synchronisation of chrome across all devices. Since the lattermost is important, and each browser does something different, we can actually use sites in Firefox that run java, for instance, all browsers must be equally functional whether on a debian Mate box, cell phone or table. It is 2017. and everyone does not expect synchro across devices, but requires it to work in the real world. Best, M
