How to Configure Workspace Sharing, Vertical Tabs, and Sleeping Tabs in Microsoft Edge

Modern web research and enterprise workflows routinely demand navigating dozens of concurrent browser tabs. However, unmanaged browser sprawl creates severe memory resource exhaustion, clutters taskbars, and complicates team collaboration when onboarding colleagues onto multi-link projects. Microsoft Edge provides a native productivity triad engineered to resolve these challenges: Edge Workspaces, Vertical Tabs, and Sleeping Tabs.

Rather than relying on third-party tab organizer extensions that present security risks or slow down browsing performance, Edge integrates these features directly into the Chromium backend. Workspaces allow teams to share live browser sessions where all members view the same curated tabs in real time without exposing passwords or cookies. Meanwhile, Vertical Tabs optimize screen real estate on widescreen 16:9 and 21:9 monitors, and Sleeping Tabs automatically put inactive background tabs into low-power states to reclaim up to 85% of browser memory. This guide details how to configure and deploy all three features.

Feature Capabilities and Productivity Matrix

Understanding how each feature addresses workflow friction ensures maximum operational benefit:

Feature	Primary Function	Productivity & Resource Impact
Edge Workspaces	Creates isolated, collaborative browser project windows shared via a single link.	Eliminates manual link copying during meetings; centralizes project documentation in real time.
Vertical Tabs	Repositions the horizontal tab strip to a collapsible left-side vertical sidebar.	Prevents tab squishing; displays readable page titles across 50+ open tabs.
Sleeping Tabs	Unloads inactive background tab render processes into an idle memory state.	Reduces RAM footprint by 50% to 85% and significantly extends laptop battery longevity.

Step 1: Setting Up and Sharing an Edge Workspace

Edge Workspaces function as persistent, cloud-synced project environments. When collaborators join a Workspace, new tabs opened by one member appear instantly for everyone in the group:

1. Open Microsoft Edge on Windows or macOS.
2. Locate the Workspaces icon in the extreme top-left corner of the browser window (or press Ctrl + Shift + S if assigned).
3. Click New workspace.
4. Assign a descriptive name (e.g., Q4 Marketing Launch) and choose a distinctive colour theme to visually separate this project window from your personal browsing.
5. Click Done. Edge opens a dedicated workspace window.
6. Open the project websites, documentation pages, and cloud spreadsheets relevant to the task.
7. Click the Invite button in the upper-left workspace header.
8. Click Copy link and dispatch the invitation link to colleagues via Microsoft Teams, Outlook, or Slack.
9. Note on Security: Workspaces share only the URLs and active tab structure. Collaborators never inherit your session cookies, saved passwords, or private browsing history. When a collaborator clicks a link, they authenticate using their own personal credentials.

Step 2: Activating and Customizing Vertical Tabs

Horizontal tab bars become unreadable when dozens of tabs compress into narrow favicon-only slivers. Vertical Tabs preserve legibility regardless of how many tabs you open:

1. In Microsoft Edge, look at the top-left corner of the tab bar.
2. Click the Turn on vertical tabs icon (an icon depicting a small window with a vertical sidebar). Alternatively, press Ctrl + Shift + , (comma).
3. The tab bar immediately transitions to a vertical rail along the left edge of the display.
4. Click the Collapse pane arrow (<) at the top of the rail to minimize the tab strip into compact favicons. Hovering over the strip smoothly expands the full titles without displacing webpage content.
5. To group related tabs inside the vertical strip, select multiple tabs (using Ctrl + Click), right-click, and choose Add tabs to new group. Assign a custom label and colour for clean hierarchical organisation.

Step 3: Configuring Sleeping Tabs for Optimal Memory and Battery Life

Inactive browser tabs consume substantial memory (RAM) and CPU cycles running background JavaScript timers and animated advertisements. Sleeping Tabs unloads idle DOM trees while preserving the tab state:

1. Click the Settings and more button (three horizontal dots) in the top-right corner of Edge and select Settings.
2. In the left navigation menu, select System and performance.
3. Under the Optimize Performance section:
   • Ensure Save resources with sleeping tabs is toggled to On.
   • Toggle Fade sleeping tabs to On. This visually dims inactive tab text in the vertical bar so you immediately recognize which tabs are suspended.
   • Set Put inactive tabs to sleep after the specified amount of time. Options range from 30 seconds to 12 hours. For balanced battery life and performance, 5 minutes or 15 minutes is ideal.
4. Configuring Whitelists: If you run critical web apps that must never be suspended (such as live audio players, CRM dashboards, or active call center softphones), click Add under Never put these sites to sleep and enter their URLs (e.g., https://meet.google.com).

Measuring System Resource Savings in the Efficiency Dashboard

To audit exactly how much memory and processor capacity Edge preserves across your active browsing session:

1. Click the Performance heart/speedometer icon in the Edge toolbar (or navigate to Settings > System and performance).
2. Review the Efficiency mode status. When running on laptop battery power, Efficiency mode automatically activates aggressive sleeping tab timeouts and throttles background animations.
3. The dashboard displays live metrics detailing the exact megabytes of RAM released by sleeping tabs over the previous 30 days.
