This is a pre-alpha build of Google Chrome on Linux. It is woefully incomplete. No work has been done on performance yet, much of the UI is missing, plugins don't work, and many more bugs remain.
Chromium is an open source browser project. Google Chrome is a browser from Google, based on the Chromium project.
Don't file bugs without doing the work
Every minute spent triaging and de-duplicating bugs is a minute spent not fixing them. If you have a good bug report (e.g. includes a stack trace or a reduced test case), first verify it exists in the latest build, then verify it hasn't been filed already, then file your bug using the Linux-specific template.
