Google is set to improve Chrome by introducing a new "Link Preview" feature. This feature, currently in development for desktop use, could significantly change how users interact with web content. 

Link Preview allows users to view a small popup web page preview simply by clicking or hovering over a hyperlink.

This preview provides users a glimpse of the content on the linked page, allowing them to decide whether to fully open the page or continue their current browsing. Not only does this save time, but it also optimizes data usage by preventing the unnecessary loading of undesired content.

 Among the options outlined in the development documents, users could open these previews in a new tab or in the Side panel, further augmenting the flexibility of their browsing experience.

One intriguing approach detailed by Google is the idea of "Ephemeral Window and Tabs". Drawing inspiration from Chrome's ephemeral tab feature for Android, this concept involves the introduction of an ephemeral/temporary window that holds multiple preview tabs within each standard tab.

In practical terms, when a user decides to fully explore a previewed page (referred to as preview tab 2), they can navigate to a new tab where the preview tab 2 will detach from the ephemeral/temporary window and convert it into a regular tab within the current window.

This feature elevates browsing efficiency by allowing users to screen content before fully engaging, refining the browsing experience to match their interests and requirements.

Privacy and security concerns

Google Chrome developer Takashi Toyoshima has also responded to questions regarding the security and privacy implications of this feature. He acknowledged concerns about potential exploitation, such as the running of harmful JavaScript in the preview window.

Toyoshima assured users that the feature will be protected by capability control mechanisms, which are already in use by the prerendering technology. Detailed behaviors of the feature are currently under discussion with Google's security and privacy teams.

Additionally, the developer highlighted that Google intends to enforce strong restrictions on cross-site activities and will consider requiring a clearer user action to trigger the preview. Furthermore, a setting to disable the feature will be available for users who prioritize privacy.

In essence, Google's goal is to provide a safer and more efficient browsing alternative to the common practice of opening multiple tabs for checking sub-articles or preloading content.

Google is internally exploring the new design in Chrome, and we don't know when it will begin rolling out to the users.
