That error description is, by far, the best error description in BigBlueButton. I'm not sure how this gets translated to _old fashioned tuga portuguese_ but running the client using the _zueira portuguese_ this translates as Ele estava logado. Por favor, tente recarregar a página.. What a gem!

@pedrobmarin should this be closed?

@matiasilva I believe the resizing source of this issue is resolved but I'm sure other things might cause similar issues at the media/presentation/cameras area. Since the issue is quite direct to the resize/firefox problem I guess we can close this one.
