    Simple Methods To Activate Tab Previews In Firefox

    Tab Previews in Firefox operate much like popular browsers such as Google Chrome, Microsoft Edge, Vivaldi, Opera, and Brave Browser. When hovering over a tab, a brief preview of the webpage appears, allowing you to quickly view the content without changing tabs.

    Although Tab Previews are present in the most recent version of Firefox, the feature is not enabled by default, possibly due to ongoing bug fixes. There isn’t a direct setting in the browser options to activate it. You’ll need to modify some advanced configurations to enable it. Here’s how to go about it:

    Enabling Tab Previews In Firefox

    1. Access the about:config page.

    2. Acknowledge the Risk and Proceed.

    3. Paste the provided text into the search bar.

    4. The default setting is set to false.

    5. Double-click to switch it to true.

    That’s all that’s necessary. There’s no need to restart the browser after these modifications. Test the feature by opening multiple tabs, hovering over them, and observing Firefox display Tab Previews. Note that this functionality is only active on open tabs. Inactive tabs will not show Tab Previews until they are brought to the forefront.

    If you find Tab Previews loading slowly, there’s an adjustable option you can modify. Search for.

    By default, it’s set to 1000ms (1 second), indicating a 1-second delay before Tab Previews appear when hovering over a tab. Lower the value to 500ms or below to reduce the delay. Setting it to 200ms will show the previews instantly.

    Firefox 123 has also introduced a new Web Compatibility Reporting Tool, another concealed feature. Follow the steps as described above and search for extensions.webcompat-reporter.enabled. Change its value to True to enable it. To utilize the tool, visit a website, click on Firefox’s Menu > Help, and you should see an option named “Report site issue.”

    If you want to view thumbnails of multiple tabs simultaneously, you can make use of the Panorama Tab Groups extension to view the previews and organize your tabs into groups. Nonetheless, having native support for Tab Previews is a positive development, eliminating the need for potentially outdated or unsupported add-ons moving forward.

    Users have long been urging Mozilla to integrate Tab Groups and Vertical Tabs into Firefox, features they anticipate being included in upcoming releases.
