Where can I find and submit bug reports on Google's Chrome browser?

Google is calling it Chromium on Google Code

The Chromium Bug Reporting Page is there and has the link to submit bugs listed. (Google Account Required)

Here's a direct link to the bug report form.

Go to the wrench -> About Google Chrome -> report an issue. (accurate as of v19.0.1084.46)

This is the home page for the Code: http://code.google.com/chromium/

And here's more info: http://dev.chromium.org/getting-involved including the bug list
