Sorry I used the wrong word. The beta I download there is 78.something
and does not match the latest one Yves was running (80 something). I
tried it already and it doesn't fail. I also found "chrome dev" which
is 79.something and doesn't present the problem either. When I go to
the "chrome canary" link, it clearly says in the middle of the screen
"we do not support linux". So for now I can't test, that's pretty sad :-/
