Chrome beta (also dev channel) should be available on Linux. See
https://www.google.com/chrome/beta/?platform=linux. (Or if you've already
gotten the apt repository added, I believe the google-chrome-beta package
should work.) It also uses a separate profile directory, so it won't
conflict with your usual install. Hopefully that'll ease testing.
