Chrome has 3 releases - a regular release, a dev release and canary. Canary is simply a much newer release thats not as well tested, but has the latest shiny stuff. After a while the version that was released in the canary channel gets any bugs that are found fixed, then filters downward to dev, and then to the regular release. Other than the lack of testing, and possibly not having all the bugs fixed, canary is merely chrome FROM THE FUTURE
In short, you get cool stuff, but it might crash horribly. On the other hand, you don't have to use it as a primary (in fact, you cannot set it as default) browser. Its mainly useful if you like living dangerously and want to test bleeding edge features
Well Canary is the latest and the rest is for stable use like others said FROM the FUTURE.
But this question is about Linux user point of view. As i am 100% (CentOS, Fedora, ArchLinux, Ubuntu, FreeBSD) user and i unfortunately do not have permanent Mac or Windows development hardware/software.
How can i get Google Canary? When someone say please debug it with only Google Canary not with Google Chrome Browser or Chromium browser???
