Multiple Chrome users syncing with the same Google Account

Solution 1:

There is no need to run multiple Chrome profiles if you want to use one and the same Google account.

Probably what you want is to run multiple separate instances of Chrome, since this would allow you to use one and the same Google account, therefore sync all the bookmarks, extensions, settings etc., but have different logins, for instance, on Facebook or any other non Google websites and services.

As of 2014-10-05, the easiest way to run multiple profiles, versions or instances of Chrome is to use Google Chrome Portable, downloaded from: http://portableapps.com/apps/internet/google_chrome_portable

Currently I'm running 4 separate instances of Google Chrome v37.0.2062.124. One instance is installed and three other instances of Google Chrome are portable.

Here's how my Windows 7 Taskbar looks like when all 4 instances of Chrome are opened and running:

If you want to change Google Chrome icon that is shown on the Windows Taskbar once Google Chrome is started, then you should follow this link: Is it possible to customize taskbar icons? If so how?

The answer is given in comments: you need to change icons that are stored in chrome.dll using Resource Tuner (use Trial version) or Resource Hacker (free).

I've used IcoFX (Trial version) to generate various .ico icons.

The use of multiple Chrome profiles DOESN'T ALLOW to use one and the same Google account, running multiple separate Chrome instances DOES.

Good luck!
