What you hope to achieve, if you were able to run it under firejail?
I want to have two profiles and be able to define myself what location chromium have access for example /media/data
With Firejail I was able to do that.
Have you tried running a non-snapped chromium first?
I have used non-snapped chromium so far, it means installed from deb. But now it is not available in 14.04 so I have to use snap chromium.
