I run WhatsApp, Messenger, and and couple of Slack channels, as separate 'applications' by using the '--app=<url>' when launching Chrome. However they are not sandboxed.
Chromium can be run in portable mode, so I guess you could sandbox apps by having separate side-by-side Chromium installs. That said, this tool is probably easier to use.
I am wondering whats the difference. So far I was able to find this explaining the flags:
profile-directory: // Selects directory of profile to associate with the first browser launched. [1]
user-data-dir: // Specifies the user data directory, which is where the browser will look for all of its state. [2]
But to be honest I am not sure I understand that completely. I mean there is also some documentation stating that the user-data-dir contains profile data[3]. Does anybody what the actual difference is?
This reminds me of Mozilla prism, which I think is discontinued now. I always liked having a separate window and process for gmail that wouldn't close if my browser crashed
Didn't know through that it was so easy to get it working with FF too. Thanks :-)
