How to disable the Tab Hover Cards in Chrome

October 28, 2019

My Chrome recently got updated and a new feature that was introduced which I found very distracting and annoying is "Tab Hover Cards", where it displays a pop-up box whenever you place your mouse cursor on a tab.

To disable this function, type this in the URL:

chrome://flags/

Then search for "tab hover" and set the settings to "Disabled":

How to use "nohup" with chained commands in Ubuntu
