[SOLVED] Run multiple, unrelated instances of Chrome?

[DoYouKubuntu]

I'd like to be able to run multiple, separate, unrelated instances of Chrome. I need to make sure they're each completely independent of each other, with no sharing, viewing, reading, writing of any config files, cookies, cache, etc.

I know my friend Google may be able to clue me in, but I figured if someone here--who's using the same OS I am--happens to know how to do this, that would be great. Anyone?

You might want to try firejail. It's in the repository. It's like running an app in chroot.
Read all about it here: https://firejail.wordpress.com/

You can use multiple profiles with any chromium based browser. Different profiles use different configs and caches.
With chromium, I use "chromium-browser --user-data-dir=$HOME/.config/profilename/" to launch a specific profile. (this is for Chromium, so edit it if you launch Chrome)
The "profilename" profiles also have their own cache directories in $HOME/.cache/.

You could probably combine that with firejail, if you wish, but firejail can be a bit tricky to configure right so it's actually effective, but not too restrictive (especially with chromium based browsers that use their own sandboxing). I wouldn't bother with it when using open-source Chromium, but Chrome is sort of different, since no one knows what the hell it does behind the scenes.

Thanks for the suggestions, guys. I think this, chromium-browser --user-data-dir=$HOME/.config/profilename/, is what I had in mind, but didn't know how to do. I have some experimenting to do!

I just wanted to update this with the solution, which @kubicle nudged me toward.

The syntax for Chrome is:

google-chrome --profile-directory=ProfileName

where ProfileName is the name Chrome assigns the profile, as found in $HOME/.config/google-chrome, not the name you gave it when creating it. So, for example, the profile that I named TestOne is called with this:

google-chrome --profile-directory="Profile 1"

Others are:

google-chrome --profile-directory="Profile 2"
google-chrome --profile-directory="Profile 3"

and so on.

Works like a charm!
