Mozilla Firefox Introduces New Tab Preview Feature

TapTechNews June 6th news, Mozilla company yesterday tweeted through the Firefox Nightly official X account, stating that in the latest Firefox browser version in the Nightly channel, a new experimental Flag has been introduced. After the user enables it, when hovering the mouse over the tab, the tab content can be previewed in the thumbnail.

Mozilla has already introduced relevant settings in the Firefox 123 stable version update, and users can enable the following experimental Flags on the about:config page:

browser.tabs.cardPreview.enabled - Set the value to true

browser.tabs.cardPreview.showThumbnails value set to true.

browser.tabs.cardPreview.delayMs specifies the delay time in milliseconds

And the latest Firefox Nightly version no longer needs to adjust the above parameters, and the tab preview function is enabled by default for all users.

TapTechNews note: Although the Firefox Nightly channel can allow users to experience various new features and functions, there are some BUGs and will lead to instability of the browser. It is not recommended for users who pursue daily use.
