Now Chromium_OSX_78.0.3904.108 installed.
I created several users on my Mac.
My main user, where Chromium doesn't work, doesn't have admin rights.
Also with the Chromium_OSX_78.0.3904.108 is the same picture.
Changed to other users on the same Mac, there didn't exist a Chromium profile.
User with admin rights - Chromium 78.0.3904.108 works.
User with no admin rights - Chromium 78.0.3904.108 works.
Back to my main user, searched for Chromium with Find_Any_File and renamed all directories and files under /Users/username/Library/, so Chromium had to create a new profile.
Also with this new profile Chromium 78.0.3904.108 did not work. What could be the reason?
But with the older Chromium 77.0.3865.120 and the same Chromium profile it works.
One of my test pages is dnssec.vs.uni-due.de
The error message:
The website is not available. The website under dnssec.vs.uni-due.de may be temporarily unavailable or has been permanently moved to a new web address.
