I launched chromium with --disable-web-security, and now whenever I click on the launcher icon in Ubuntu 16.04, Chromium launches with this option.

How to remove this option, to launch Chromium normally again?

  • Really sorry, I was mess up with all my questions. I ened up editing the content of the .desktop file to enable web security thanks to your answer ! – Louis Jan 25 '17 at 13:47

Quick & short answer

Chromium obviously created a local .desktop file in ~/.local/share/applications, running Cromium with the option you mention (both Google-Chrome and Chromium are quite "productive" when it comes to producing local .desktop files).

Simple solution is to remove any local .desktop file(s) in ~/.local/share/applications, referring to Chromium (you don't need them if you didn't deliberately create them locally), log out and back in before running Chromium again.


~/.local is a hidden folder by default. Press while in your home directory (in nautilus) Ctrl+H to make it visible.

Background information

Local .desktop files overrule global ones in /usr/share/applications. If applications produce local .desktop files in ~/.local/share/applications (some applications do), functionality may change, compared to the original one.

This obviously was the case in your situation.
