Microsoft has adopted the Chromium open source project in the development of Microsoft Edge on the desktop to create better web compatibility. This new Microsoft Edge runs on the same Chromium web engine as the Google Chrome browser, offering you best in class web compatibility and performance.
The new Chromium based Microsoft Edge is supported on all versions of Windows 7, Windows 8.1, Windows 10, Windows Server (2016 and above), Windows Server (2008 R2 to 2012 R2), and macOS.
It’s easy to end up with a ton of tabs open. The more you have open, the more difficult it becomes to find, switch between, and manage them. With vertical tabs, you can easily shift to view your tabs in a pane to the side. This allows you to easily see the titles and access controls like mute and close. It even makes it easy to reorder your tabs, with the ability to drag and drop to rearrange. When you want to focus on a specific page, you can collapse the pane. Anytime you need to switch between tabs, you can hover over the pane to see all the information you need. The new Microsoft Edge is the only browser to offer built-in vertical tab navigation allowing for a more streamlined experience.
Starting with the Microsoft Edge Beta, Dev, and Canary channels, you can now resize the vertical tabs pane. Microsoft Edge will open the vertical tabs pane the same size as it was when last closed or turned off.
If vertical tabs is pinned, you will have the vertical tabs pane always show the size you set.
If vertical tabs is unpinned, the vertical tabs pane will stay collapsed by default and automatically expand open to the size you set whenever you hover the pointer over the collapsed vertical tabs pane.
This tutorial will show you how to enable or disable vertical tabs auto expand when collapsed in the Chromium based Microsoft Edge.
