If you have just updated your Google Chrome, you will see a new thing every time you hover your mouse over a tab. You will see a popup containing the information regarding the webpage on the tab (URL and the title page). This new feature is called Tab Hover Cards and is enabled by default. If you find this card annoying, you can disable it.
The Tab Hover Cards feature started available on Google Chrome version 78. This feature replaces the tooltip you used to see on the older version of Google Chrome every time you hover your mouse over a tab. To disable the Tab Hover Cards feature, you need to go the Flags menu of Google Chrome by typing the following address on the address bar.
The address above will take you directly to the Tab Hover Cards section on the Chrome Flags. To disable the feature, click the dropdown menu and select Disable.
You need to restart your Google Chrome to apply the new change. You can click the Relaunch button on the bottom-right corner to restart your Google Chrome.
Please note that while you can disable this feature, it might be enabled again once a new Google Chrome version is rolled out unless you disable the auto-update of Google Chrome on your computer.
