Edge Browser in 2026: Features, Download, and Tab Safety

Microsoft has spent years trying to convince people that Edge isn’t the old, sluggish browser some of us remember. As of September 2026, that argument has gotten stronger: Edge now runs on the same Chromium engine as Chrome, adds a handful of genuinely useful extras like Workspaces and Split screen, and comes free on every major platform Microsoft supports. This guide covers what the Edge browser actually does today, how to get it, where it’s stronger or weaker than Chrome, and (because no browser guarantees you’ll never lose a window of tabs) how to make sure your open tabs survive a crash, an update, or a bad click regardless of which browser you land on.

What Is the Edge Browser?

Edge is Microsoft’s free web browser, built on the Chromium engine, available on Windows, macOS, Linux, iOS, and Android. Microsoft’s own release notes describe each Edge update as incorporating “the latest Security Updates of the Chromium project,” which is the company’s own confirmation that Edge shares its rendering core with Chrome rather than running Microsoft’s older, discontinued EdgeHTML engine.

As of this session’s check against Microsoft’s release-notes page, the current Edge Stable build is version 154.0.4258.37, released 24 September 2026. Microsoft doesn’t publish a single page listing exact minimum RAM or CPU requirements, so treat any specific system-requirement number you see elsewhere with some skepticism.

Here’s the shape of it at a glance:

Chromium, not Chrome. Edge and Chrome share an engine, not a codebase. Microsoft builds its own features (Workspaces, Copilot, Edge Secure Network) on top of Chromium independently of Google.

How Do I Download and Install Microsoft Edge?

You get Edge directly from Microsoft, for free, with no separate purchase step. If you searched for the microsoft edge web browser download, microsoft browser edge download, or any variant like download microsoft browser edge, download browser microsoft edge, web browser edge download, or simply web browser edge, they all lead to the same place: Microsoft’s own Edge page, where the installer for your operating system is one click away.

If you’re on Windows, Edge is often already installed as the system default, so you may just need to open it rather than download anything. On Mac and Linux, the download step is unavoidable, and it’s worth grabbing the installer straight from Microsoft rather than a third-party mirror site, since that’s the only place you can be sure the build is current and unmodified.

Is Edge Built on Chromium, and What Does That Mean for You?

Yes, Edge is Chromium-based, and Microsoft says so itself in its release notes. That single fact explains most of what makes Edge feel familiar if you’ve used Chrome, and it’s worth understanding before you decide which browser fits your workflow.

Chromium is the open-source project that also underpins Chrome, Brave, Opera, Vivaldi, and (per their own vendor statements) Arc and Dia. Sharing an engine means these browsers render web pages the same way, support the same web standards, and, in most cases, can run extensions built for the same store. It does not mean they behave identically: each vendor layers its own features, defaults, and business model on top.

For you as a user, the practical upshot is that switching from Chrome to Edge (or the reverse) rarely breaks a website you rely on, since both browsers interpret the page the same way underneath. What changes is the interface around that page: Edge’s Workspaces panel, its Copilot sidebar, its Sleeping tabs settings, and its sync options all sit on top of the shared Chromium core. If you’re weighing the two head to head, the detailed comparison in our Chrome vs Edge breakdown goes further into specific trade-offs than this overview does.

Chromium basis, separate security track. Sharing Chromium doesn’t mean every Chromium browser updates on the same schedule or with the same rigor. Arc, for instance, has said publicly it now receives Chromium updates only, not active security patches — a reminder to check a browser’s own update cadence before trusting it with sensitive work.

What Features Make Edge Different From Chrome?

Edge’s main differences from plain Chrome are Workspaces, Split screen, Copilot, and Sleeping tabs, all built by Microsoft on top of the shared Chromium engine. None of these exist in stock Chrome, which is the closest thing Edge has to a genuine selling point beyond “it’s Chromium, but free and pre-installed on Windows.”

Workspaces lets you keep browsing tasks and tabs organized in separate, named, color-coded groups — useful if you juggle a work project and personal research in the same window and want a visual line between them. Split screen displays two pages side by side inside a single tab, so you can, say, read documentation on one side and fill out a form on the other without alt-tabbing between windows. Copilot is Microsoft’s AI assistant, wired into the browser itself. Sleeping tabs quietly frees up memory from tabs you’ve stopped looking at.

None of these features are backup tools, and it’s worth being honest about that distinction. Workspaces organizes tabs you already have open; it doesn’t protect them if the window closes by accident or the browser crashes mid-update. Keep that separation in mind as you read the sections below on performance and sync.

How Good Is Edge’s Performance and Battery Life?

Edge’s own marketing describes it as “the only browser optimized for superior performance on Windows,” backed by three specific features: Startup Boost, Sleeping tabs, and Energy Saver. Whether that claim holds for your setup depends heavily on your hardware and how many extensions you run, but the individual features are real and independently useful.

Startup Boost is designed to make Edge open faster by keeping certain background processes ready. Energy Saver, per Microsoft’s own copy, provides “an average of 25 more minutes of battery life” — a modest but real gain on a laptop running low mid-flight or mid-meeting. Sleeping tabs is the most detailed of the three: Microsoft’s support page describes it as pausing background tabs after two hours of inactivity by default, and a 2020 measurement from Microsoft’s own Edge engineering blog found it reduces memory usage by roughly 32% on average and CPU usage by roughly 37%, compared with tabs that stay fully active.

1. Open Settings and more. Click the three-dot menu in the top-right corner of Edge.
2. Go to Settings, then System and performance. Scroll to the Performance section.
3. Turn on “Automatically put tabs to sleep.” Adjust the inactivity timer if you want tabs to sleep sooner or later than the two-hour default.

Sleeping tabs and Startup Boost solve a real problem (too many active tabs eating memory) but they’re not a substitute for saving what those tabs are. A sleeping tab still disappears if you close the window by mistake or Edge needs to restart for an update. That’s a separate problem, and it’s one built-in performance features aren’t designed to solve.

What Privacy and Security Tools Does Edge Include?

Edge bundles a handful of security and privacy tools directly into the browser, without needing extensions. Microsoft names Microsoft Defender SmartScreen for phishing and malware blocking, plus Edge Secure Network, described as a built-in VPN service, and an Enhanced security mode you can toggle on for stricter defaults.

Defender SmartScreen works in the background, checking sites and downloads against known threat lists before you land on them or run a file. Edge Secure Network is notable because a built-in VPN isn’t something Chrome offers natively. It’s one of the areas where Edge’s extra layer on top of Chromium is a genuine, practical addition rather than a cosmetic one. Microsoft’s page doesn’t detail data caps or country restrictions for Edge Secure Network in the source this guide relies on, so if that matters for your use case, check the settings panel directly rather than assuming unlimited use.

Edge also includes InPrivate browsing, which behaves like the private/incognito modes found in every major Chromium browser: it doesn’t save your history, cookies, or site data locally once you close the window. None of these tools, including InPrivate mode, back up your tabs — InPrivate specifically avoids keeping any record at all, which is the opposite of what you want if the goal is not losing a window of research.

Privacy features and tab safety are different problems. Defender SmartScreen and Edge Secure Network protect you from threats while you browse. They don’t protect the tabs themselves from disappearing. BelayTab handles that second problem separately, with no host permissions and nothing sent off your computer unless you turn on Sync.

What Is Copilot in Edge, and Should You Use It?

Copilot in Edge is Microsoft’s built-in AI assistant, and Microsoft describes it as using “the context of your open tabs to compare options, explain what matters, and complete tasks.” In practice, that means Copilot can read what’s on the pages you have open and use that as context for a question, without you needing to copy and paste content into a separate chat window.

Microsoft also names a Copilot Vision mode, described as enabling analysis of what’s on your screen or in an open tab, plus a handful of adjacent AI tools: a scareware blocker, an image generator, automatic tab organization, and theme generation. These sit under the same Copilot umbrella but serve fairly different purposes — the scareware blocker is a security feature dressed up with AI framing, while the image generator and theme generator are closer to novelty add-ons than daily-use tools for most people.

Whether Copilot is worth turning on depends on how you browse. If you regularly compare options across a dozen open tabs (flights, apartments, product reviews) having an assistant that can read that context without you re-explaining it each time is a real time-saver. If your browsing is mostly single-purpose (reading one article, checking one account), Copilot adds a sidebar you’ll rarely open. It’s worth trying for a week before deciding either way, since it’s built in at no extra cost and easy to ignore if it doesn’t click for you.

One caution worth stating plainly: an AI assistant reading your open tabs’ context means it’s seeing what’s on those pages. If you’re working with anything sensitive, it’s reasonable to close those tabs or use InPrivate mode before opening Copilot, the same judgment call you’d apply to any AI tool with page access.

How Does Edge Sync Work Across Devices?

Edge syncs your passwords, favorites, and settings across devices when you’re signed in with a Microsoft account, according to Microsoft’s own Edge page. That’s the extent of what Microsoft’s own copy specifically promises — and it’s worth noticing what isn’t explicitly listed there: open tabs.

This distinction matters more than it might seem. Chrome’s own comparable page explicitly states that signing in syncs “bookmarks, saved passwords, and tabs” across devices — tabs named directly. Edge’s own page, as fetched for this guide, does not use that same specific wording for tabs. That doesn’t necessarily mean Edge has zero tab-syncing capability tucked into its settings, but it does mean you shouldn’t assume it works the same way Chrome’s does, or rely on it as your safety net without checking Edge’s own sync settings menu for yourself.

If you want a guarantee that a specific set of tabs (say, the ten tabs you had open for a project last Tuesday) will still be there next week on any machine, sync settings aren’t really built for that job anyway. Sync mirrors your current state forward; it’s not designed to preserve a snapshot from a point in time. That’s a session-management problem, not a sync problem, and it’s the gap BelayTab is built to close: named, dated sessions you choose to keep, independent of whatever your current open tabs happen to be.

Don’t rely on sync as a backup. Syncing settings across devices is convenient, but it mirrors your current state. It doesn’t keep a history of past states. If you need last week’s ten research tabs back specifically, sync alone won’t get you there.

How Many People Actually Use Edge?

Edge holds roughly 10.46% of worldwide desktop browser usage and about 5.36% across all platforms combined, according to StatCounter Global Stats for August 2026, the latest full month available. That puts Edge a clear second on desktop, behind Chrome’s 73.28% but ahead of Firefox’s 5.31% and Safari’s 5.24% in that same desktop breakdown.

The gap between Edge’s desktop share and its all-platform share tells its own story: Edge’s strength is largely a Windows-default effect. It comes pre-installed on every modern Windows machine, and plenty of people simply never switch away from whatever loads when they click the browser icon. On mobile, where Edge competes on equal footing with Chrome and Safari rather than benefiting from being the factory default, its share is much smaller, since Safari dominates iPhone usage and Chrome dominates Android.

None of this is a judgment on Edge’s quality — default-browser inertia is real and affects every operating system’s bundled browser similarly. It’s just useful context if you’re deciding whether to invest time customizing Edge: you’d be joining roughly one in ten desktop users, a meaningfully large but clearly secondary position to Chrome’s.

What Are the Trade-Offs of Choosing Edge Over Chrome?

Edge’s trade-offs come down to a smaller extension ecosystem and lower overall usage versus a handful of genuinely useful built-in extras. Because Edge and Chrome share the Chromium engine, most day-to-day browsing feels identical between them — the differences show up at the edges, literally and figuratively.

On the plus side, Edge gives you Workspaces, Split screen, Copilot, a built-in VPN, and Sleeping tabs without installing anything extra, and it’s free on every platform Microsoft supports. Windows users in particular get tighter integration: Xbox Game Bar overlay support, Microsoft 365 integration, Bing search enhancements, and Microsoft Rewards earning are all named on Microsoft’s own Edge page as additional perks for people already inside the Microsoft ecosystem.

On the downside, Edge’s much smaller market share (5.36% overall against Chrome’s 69.39%, per StatCounter) means fewer people testing edge cases and troubleshooting guides written specifically for it, though the shared Chromium base softens that gap considerably since most Chrome fixes apply. If you’re deeply invested in Google’s ecosystem (Gmail, Drive, Chrome’s own AI features) switching browsers won’t change which account you’re signed into, but it can mean an extra sign-in step here and there. And whichever of these you land on, our broader best-browser comparison is worth a read if you’re still deciding between more than just these two.

How Do You Protect Your Tabs and Sessions in Edge?

You protect Edge tabs the same way you’d protect any browser’s tabs: by saving them somewhere that survives a crash, an accidental close, or an update, since Edge’s own built-in tools aren’t designed for that job specifically. Sleeping tabs and Startup Boost manage performance. Sync, as covered above, mirrors settings rather than preserving history. Neither one is a backup.

This is where BelayTab fits in, and it works in Edge because Edge is one of the Chromium browsers BelayTab supports directly, alongside Chrome, Brave, Opera, Vivaldi, Arc, and Firefox, plus Safari on Mac. It’s free, requires no account, and has no limit on sessions or tabs. Save a window with one click or with Ctrl + Shift + S (Cmd + Shift + S on Mac), and BelayTab keeps your Workspaces’ tab groups, pinned tabs, and tab order intact in the saved session.

Beyond manual saves, BelayTab saves a snapshot of every open window on its own every five minutes, and again the moment you close a window, so an Edge crash or a surprise update restart doesn’t have to mean starting over. It also keeps the last 20 versions of each session (restoring never overwrites a version, it just adds a new one) plus a 30-day trash for anything you delete on purpose or by accident. All of that lives on one Recovery screen alongside your snapshots, deleted sessions, and Edge’s own recently closed windows list, so you’re not hunting across three different menus to find a tab you lost yesterday.

1. Install BelayTab from the Edge add-ons store. Find it on the download page and add it to Edge in a couple of clicks.
2. Save your first session. Click the BelayTab icon or press Ctrl + Shift + S, name the window, and choose whether to keep the tabs open or close them.
3. Check the Recovery screen anytime. Open it to browse snapshots, deleted sessions, version history, and Edge’s own recently closed windows in one place.

BelayTab doesn’t fix a frozen Edge window or recover tabs from before it was installed (no extension can do either of those things) but it does make sure that from the moment it’s running, your Edge sessions are backed up automatically, without you having to remember to do anything. If you also use other browsers day to day, the optional paid Sync tier ($4/month or $36/year, with a 30-day refund) carries those same sessions across every browser you’re signed into, with 90 days of cloud version history and web access at app.belaytab.com.
