You may see an error from time to time on an Android phone projected by curbi where curbi tells you that an app is blocked with the message "Non curbi browsers are blocked".


This can happen if you have used an app in the past to download a file.  When a file is downloaded on an Android device, Android opens the Chrome browser to take care of the download.


From that point on, the app and the Chrome browser are linked to run together, so curbi sees Chrome running.


To get around this problem, just shut the app in question from the standard app switcher.  Once you have done this, the app will no longer be linked with Chrome and it will be able to open normally.
