Microsoft began pushing a major update to its Edge browser on May 13, 2026, supercharging Copilot with the ability to see open tabs, mine browsing history, and proactively suggest information based on the user’s current session. The rollout—dubbed the “Browse with Copilot” expansion—lands on desktop (Edge 134.0.3124.93) and mobile versions simultaneously, transforming the AI assistant from a sidebar helper into a browser-wide copilot.

This isn’t just a cosmetic tweak. Copilot can now read the content of every open tab, cross-reference it with the last 30 days of browsing history, and surface contextual recommendations without a prompt. For power users, it means a more intelligent command center for research, shopping, and troubleshooting—but it also raises sharp questions about how much of our digital lives we’re willing to hand over to an AI.

What’s New: A Trio of Contextual AI Features

The update introduces three interconnected capabilities that mark a departure from the reactive, chat-based Copilot of earlier Edge versions.

1. Tab-Aware Copilot

The most eye-catching addition is tab awareness. When you open the Copilot sidebar (now accessible via the new top-right icon or shortcut Win+Shift+C), it lists all open tabs and offers to summarize, compare, or extract information from them collectively. For instance, if you have five tabs open with laptop reviews, Copilot can generate a comparison table without you having to copy-paste links or text. It can also answer questions like “What’s the difference in warranty between the Dell and HP models I’m viewing?” by scanning both pages.

Behind the scenes, Edge uses on-device semantic indexing to build a real-time content map of open tabs. Microsoft says this processing stays local until a query triggers a cloud-based model. The feature respects InPrivate and Guest tabs—those remain invisible to Copilot.

2. Browsing-History-Driven Suggestions

Copilot now pulls from the last 30 days of your browsing history (by default) to offer proactive tips. If you spent 45 minutes researching “best noise-cancelling headphones” last week, Copilot might show a card saying “Continue your headphone hunt—prices on Sony WH-1000XM7 just dropped.” This leverages the Bing-powered shopping index combined with local history signals.

Users can adjust the history window (7, 30, 90 days) or disable history access entirely via Settings > Privacy, search, and services > Copilot in Microsoft Edge. The feature uses differential privacy techniques, according to Microsoft, so individual browsing patterns are not exposed to external servers in raw form.

3. Browse with Copilot

The marquee feature is a dedicated floating Copilot button that appears on the right side of the address bar whenever you’re on a dense webpage—think product specs, long-form articles, or research papers. Clicking it triggers an inline summary, key points, and “Questions to ask” tailored to the page. It can also perform actions like “Add all action items to a new collection” or “Find similar scholarly articles.”

This is reminiscent of Arc Browser’s “Boost” but with a generative twist. Edge handles it by sending the page’s accessible text (cleaned of scripts and images) to Microsoft’s Azure OpenAI Service, with a strict “no-retention” policy on prompts and responses, per the company.

Privacy: The Elephant in the Room

The update immediately drew scrutiny from privacy advocates and everyday users alike. Granting an AI access to live tab content and weeks of browsing history touches on some of the most sensitive data a browser holds. Microsoft’s official statement reads: “Copilot in Edge processes data with user consent and always respects your privacy choices. No browsing history or tab content is used to train foundation models.”

Yet the opt-in model varies by feature. Tab-aware Copilot is enabled by default during the update, though it won’t read tabs until you explicitly invoke the sidebar. Browsing-history-driven suggestions, however, are on by default; users must navigate to settings to opt out. The “Browse with Copilot” button is page-specific and activates only on click, but it sends the full page text—minus login forms and sensitive fields, according to Microsoft—to Azure servers.

Security researcher Danilo Franzoni tweeted: “Even with promises of local-first processing, handing a browser AI the keys to your tab data is like letting a stranger read over your shoulder. The attack surface just got a lot larger.” Others pointed out that enterprise environments with strict DLP policies may need to disable these features via Group Policy or Intune, and Microsoft has published the necessary administrative templates.

Community Reaction: Mixed Emotions

On the WindowsForum thread that accompanied the announcement, early adopters shared a range of experiences. User TechLawyer82 wrote: “The tab comparison tool saved me an hour during a contract review. But I had to turn off history suggestions—too creepy seeing my weekend travel research pop up during a Monday morning work session.”

Another poster, SysAdmin_Dan, flagged a performance concern: “Edge memory usage spiked by 400 MB after the update. Disabling ‘tab indexing for Copilot’ in flags brought it back to normal.” Microsoft acknowledged a known issue where the semantic indexer uses more RAM than intended and promises a fix in the next point release.

Several users also complained that the floating Copilot button on the address bar cannot be removed without disabling the entire feature, hurting their minimalist browser aesthetic. “I don’t mind Copilot, but the omnipresent button is annoying—give us a context-menu-only option,” demanded PixelPusher2025.

How to Control the New Features

For those who want to tailor the Copilot experience, Edge 134 offers granular controls:

  • Tab sharing: Go to edge://settings/privacy and toggle “Allow Copilot to read content from open tabs.” Disabling this still lets you use Copilot manually but prevents automatic tab context.
  • History-based suggestions: Under the same menu, switch off “Use browsing history to personalize Copilot suggestions.” You can also set a shorter retention window.
  • Browse with Copilot button: Currently no dedicated toggle, but you can hide the button by going to edge://settings/appearance and turning off “Show Copilot on pages.” This also removes the sidebar icon, though the shortcut still works.
  • Enterprise GPOs: New policies available under “EdgeUpdate” in the ADMX templates include CopilotTabAccessEnabled, CopilotHistorySuggestionsEnabled, and CopilotOnPageActionEnabled.

Performance and Compatibility

The update is available on Windows 10/11 (22H2 and later) and macOS Ventura or newer. Mobile users on iOS 18.2+ and Android 15+ get a subset of features: tab awareness works only if tabs are grouped, and history suggestions stay opt-in due to OS restrictions. In benchmark tests, tab indexing added roughly 5–7% CPU overhead during page loads, settling to idle within 10 seconds on a Core i7-14700K with 32 GB RAM.

Edge’s Copilot also now plays nicer with extensions. While some privacy-focused extensions like uBlock Origin and Privacy Badger may block Copilot’s API calls if filters aren’t updated, Microsoft collaborated with top extension developers to whitelist the necessary endpoints. Users of aggressive content blockers should refresh their filter lists post-update.

Competitive Landscape

Microsoft is hardly alone in baking AI into the browser. Google Chrome’s “Help Me Read” and “Help Me Write” have been in beta since late 2025, but Chrome’s tab-stuffing AI is still under Labs flags. Brave’s open-source Leo assistant offers page summaries and history interactions with local models, setting a higher privacy bar. Vivaldi’s integrated AI panel also emphasizes user-controlled data.

Edge’s advantage is its deep integration with Windows, Microsoft 365, and Bing. The new “Browse with Copilot” can directly insert content into Word documents or OneNote notebooks, and summon Cortana-like reminders based on what you’re viewing. The question is whether productivity gains outweigh the unease of constant data processing.

What’s Next

According to the Edge roadmap shared with Windows Insiders, the next phase will bring “cross-device Copilot memory,” where prompts and context from one device follow you to another, and “Voice to Copilot” on desktop, allowing hands-free queries. These features will amplify both usefulness and privacy stakes.

For now, Edge users can decide how much Copilot sees. The rollout is staggered—if you don’t see the features yet, navigate to edge://settings/help and force an update. Those who prefer to keep their browser AI-free can disable all Copilot integrations with a single toggle under edge://settings/privacy.

As browsers morph from static viewers into active information brokers, each feature update tests our comfort with algorithmic assistance. Microsoft’s latest push makes Edge a powerful research tool, but it also turns up the volume on an enduring conversation: when the browser knows everything you’re looking at, who else does?
