In modern versions of Google Chrome, whenever you rest your mouse cursor over an inactive tab at the top of your browser window, a massive preview card pops up. This “Tab Hover Card” displays the full title of the webpage, the domain name, and a large, generated image thumbnail preview of the website’s current state.
While Google introduced this feature to help users identify tabs when they have dozens open and the titles are truncated, it can be highly intrusive. The large popup covers the address bar and top bookmarks, and the constant flashing of image thumbnails as your mouse moves across the top of the screen is visually distracting. Furthermore, if you are working on a slower computer, rendering these image thumbnails can cause noticeable interface lag. If you prefer a clean browser interface, you can completely disable these preview cards.
Disabling Tab Hover Cards via Chrome Flags
Because Google considers this a core interface feature, there is no simple toggle for it in the standard Chrome Settings menu. You must disable it using Chrome’s hidden “Flags” configuration page.
- Open the Google Chrome web browser on your computer.
- Click inside the address bar (the URL bar at the top), type
chrome://flags, and press Enter. You will be taken to a page with a stark warning about experimental features. - At the top of the Flags page, you will see a “Search flags” search box. Click inside it and type Tab Hover Card Images.
- The list will filter down to show the specific setting. Next to it, you will see a dropdown menu that is likely set to “Default” or “Enabled.”
- Click the dropdown menu and select Disabled.
- Chrome requires a complete restart to apply this interface change. A large blue Relaunch button will appear at the bottom of the screen. Click it.
When Chrome restarts, the massive image thumbnails will be gone. Depending on your exact version of Chrome, hovering over a tab will now only display a small, classic text tooltip containing the name of the webpage, restoring a much cleaner, faster browsing experience.
