JustOneTab allows just one tab in Chromium/Chrome Browser and automatically close other inactive tabs.
So it makes better for executing a lot of command like this;
chromium-browser http://kiosk.url/?id=test
Install:
Copy hmloopgjggbbkfimjakahgehbljcldnl.json and JustOneTab.crx to
/usr/share/chromium-browser/extensions in ubuntu for other OS and detail
OR:
How does one install an extension for Chrome browser from the local file system?
