Revamped Vertical Tabs in Microsoft Edge: A Look at the Changes
For some time now, vertical tabs have been an integral feature of Microsoft Edge, enabling users to arrange their tabs vertically along the left side of the browser. While not every user takes advantage of this layout, it clearly serves a dedicated audience, which is evidenced by Microsoft’s commitment to enhancing it rather than phasing it out. Recent experiments have introduced a new layout under the moniker “Project Jupiter.”Let’s dive into these exciting updates!
Recently, browser researcher Leopeva64 uncovered hints of this redesign in an experimental build of Edge, specifically within the Canary version, which is known for its frequent updates and new feature testing.
The latest Canary build has unveiled a corresponding flag labeled “Project Jupiter,” whose description states: “Enables revamped appearance for vertical tabs,” identified by the ID #edge-project-jupiter.

Key Changes in Vertical Tabs
The most prominent transformation is how the vertical tab bar is now distinctly situated as a separate section. Previously, it resided below the URL bar, but the new design clearly delineates it from the rest of the browser interface, creating a more streamlined navigation experience, especially when using maximized mode.
In contrast to past iterations where features melded within the main browser area, the new layout allows vertical tabs to stand apart. For instance, the previously included Tab Actions button has been eliminated, replaced by your Profile icon located conveniently next to the More Settings icon in the URL bar, right beside the Copilot icon.

Another significant enhancement is the incorporation of the Search tabs feature at the top of the new layout. Previously, activating this feature required multiple clicks through the Tab actions menu, presenting as a floating window in the center of the browser. The new layout brings this option right to the forefront, quickening access for users.
Moreover, previously available options found in the Tab actions menu have now migrated to the three dots (…) menu, with certain functionalities accessible through right-click context menus for vertical tabs. All features associated with Workspaces are consolidated under a dedicated button, complete with a new organization tool for tab management.
When juxtaposed against the stable channel layout, the new Project Jupiter configuration appears significantly more user-friendly. The options are organized neatly, eliminating the previous clutter of overflowing menus and floating windows. Once this feature becomes widely available, users will undoubtedly appreciate the thoughtful design choices made to enhance usability.
As Edge users in Windows 11 await the opportunity to experiment with this vertical tab redesign, there’s a hope for an introduction of modern touches such as Fluent Design or Mica aesthetics. Recent discoveries hint at additional flags tied to the abandoned Project Phoenix—perhaps promising further cosmetic enhancements.
