Download Chromium
You can test Chrome builds or Chromium builds. Chrome builds have the most infrastructure for analyzing crashes and reporting bugs. They also auto-update as new releases occur, which makes them a good choice for most uses. The Chrome Canary is available for Windows and Mac and autoupdates once a day (about every 60 revisions). Other channels are available.
Downloading continuous Chromium builds.
Chromium builds do not auto-update, and do not have symbols. This makes them most useful for checking whether a claimed fix actually works. The most recent Chromium build from the build waterfall is available at http://download-chromium.appspot.com. Use the following instructions to find earlier builds:
1. Head to http://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html
2. Choose your platform: Mac, Windows, Linux, ChromiumOS
3. Pick the Chromium build number you'd like to use
---1. The latest one is mentioned in the LAST_CHANGE file
4. Download the zip file containing Chromium
5. There is a binary executable within to run. ( $ ./chrome )
Please, file bugs as appropriate. http://code.google.com/p/chromium/issues/entry
