> is there a way of holding a video- or an audioconference with Firefox (or Vivaldi) on Devuan? The ones I have come in contact with. such als
https://global.gotomeeting.com/, work only with Windows or Mac and Chrome.
If you have got Devuan, you do not have to resort to browsers for conferencing.
As for audioconferencing or one-to-one video :
qtox or another tox protocol client of your choice is the right tool.
It is also available on most other platforms, for you contacts which are not on *n*x.
