In Firefox, the function of viewing tabs will appear / Habr
In the nightly builds of the Firefox browser, the function of viewing tabs has appeared. With its help, users will be able to quickly navigate through many open websites. The feature will be included in the Firefox 124 release.
The preview opens when you move the cursor over the tab. After that, the user will see a small window showing the content of the page. In addition, the site name and link will be displayed at the top of the window.
The feature will be disabled by default. To activate, you need to add
about:config. Users will be able to control the delay between hovering the cursor and the preview window appearing using a parameter
browser.tabs.cardPreview.delayMs. In the basic configuration, a delay of 1000 ms is set.
Firefox 124 is scheduled for release on March 19, 2024, and Firefox 123 will be released on February 20 of the same year.
