q: How can I install multiple copies of Chrome so that I can use them for different Google accounts and install different extensions?
a: The easiest way we've found is Parhelia's Google Chrome Backup. It let the user install three different copies of Chrome with different extensions and accounts and bookmarks.
UPDATE: Sadly, this application doesn't seem to work anymore. We could only get it to complain that we didn't have Chrome updated or even installed. These instructions work so much better and explain how to do it yourself so you can repeat the process:
