My laptop fan used to spin up just from opening a news site in Edge — a dozen ad slots loading, autoplay video buried somewhere, the whole page fighting itself to render. Using Edge extensions to block ads fixed most of that, and the page load difference wasn’t subtle. So here’s what actually works, what Edge already does on its own, and where people waste time on settings that don’t do much.
Quick Answer
- Edge has no built-in full ad blocker — Tracking Prevention reduces some ad-related trackers but won’t hide ads themselves
- Install a real ad-blocking extension from the Microsoft Edge Add-ons store (uBlock Origin, AdGuard, and AdBlock are the common picks)
- Combine it with Tracking Prevention set to Strict for a second layer
- Ad blockers genuinely improve load speed because the browser stops downloading and rendering ad content, not just hiding it visually
- Whitelist sites you want to support (some rely entirely on ad revenue) instead of blanket-blocking everything
Why Edge Doesn’t Block Ads By Default
This trips people up because Edge does have privacy features that sound like ad blocking but aren’t quite the same thing.
Tracking Prevention is Edge’s built-in privacy feature, and it operates on three levels — Basic, Balanced, Strict. It blocks third-party trackers that follow you across sites for targeted advertising. And that can incidentally reduce some ads, since a chunk of ad delivery relies on tracker scripts. But it’s not designed to strip visible ad content off a page, and it won’t stop first-party or contextual ads that don’t rely on cross-site tracking.
Pop-up and redirect blocking is separate again — it stops forced new windows and unwanted redirects, which is more of an intrusive-ads problem than a general-ads problem.
So if you’re expecting Tracking Prevention alone to give you an ad-free browsing experience, that’s not really what it’s built for. You need an actual extension for that.
Comparing Edge’s Built-In Options vs Extensions
| Feature | Tracking Prevention (Strict) | Pop-up Blocking | Ad-blocking Extension |
|---|---|---|---|
| Blocks visible banner/video ads | No | Only pop-up format | Yes |
| Blocks cross-site trackers | Yes | No | Usually, as a secondary feature |
| Affects page load speed | Slight improvement | Minimal | Noticeable improvement |
| Setup effort | Built-in, one toggle | Built-in, one toggle | Install from Add-ons store |
| Site compatibility issues | Rare | Rare | Occasional, depends on extension |
Step-by-Step: Setting Up Ad Blocking in Edge
Step 1: Turn On Tracking Prevention First
Settings > Privacy, search, and services > Tracking prevention > Strict. This is the foundation layer — do this even before installing anything, since it costs nothing and catches some tracking that extensions might miss depending on their filter lists.
Step 2: Open the Microsoft Edge Add-ons Store
Click the three-dot menu > Extensions > Open Microsoft Edge Add-ons website, or go there directly through Edge’s extensions page. Stick to this official store rather than sideloading anything — extensions here go through a review process, and that matters more than people think for something with this much access to every page you visit.
Step 3: Pick an Ad Blocker
uBlock Origin is the one most people in tech circles recommend — lightweight, open source, doesn’t have a “acceptable ads” whitelist baked in by default. AdGuard and AdBlock are the other common picks, both solid, though AdBlock’s default settings allow some “acceptable ads” through unless you change that in its options.
Step 4: Install and Pin It
Click Get, confirm the install, then pin the extension icon to your toolbar so you can see it working and toggle it per-site when needed. This last part matters more than it sounds — you’ll want quick access for sites that break when ads are blocked.
Step 5: Whitelist Sites You Want to Support
Most ad blockers let you disable blocking for specific domains. If there’s a site whose content you actually value and that clearly runs on ad revenue, whitelisting it takes ten seconds and keeps them funded. Not a moral lecture, just worth doing occasionally.
What Actually Worked For Me
I went through three different extensions before settling, and not because the first ones were bad exactly — I just wanted to see what the actual performance difference looked like. AdBlock Plus was first, worked fine, but noticeably let more stuff through than I expected because of the default acceptable-ads setting, which I didn’t realize was on until I dug into the options menu.
Switched to uBlock Origin after that, and honestly the difference in page weight was bigger than I expected. Ran the same handful of news sites through both with dev tools open, tracking network requests — uBlock blocked noticeably more of the ad-server calls than AdBlock Plus did on default settings. That’s not a scientific study, just my own side-by-side, and your mileage may vary depending on which sites you actually visit and what filter lists each extension is running.
Advanced Fixes and Edge Cases
Some sites detect ad blockers and prompt you to disable them. This is increasingly common, and it’s a cat-and-mouse thing — filter list maintainers usually patch around detection scripts within days, but there’s sometimes a gap. If a site you need is blocked from loading, whitelist it rather than fighting the detection.
Multiple extensions running at once can conflict. Running an ad blocker plus a separate tracker blocker plus a privacy extension sometimes causes double-processing on every page load, which can actually slow things down rather than speed them up. Check Task Manager (Shift+Esc in Edge) if pages feel sluggish after adding several extensions — you’ll see per-extension resource usage there.
Custom filter lists in uBlock Origin’s advanced settings let you add region-specific or niche filter subscriptions beyond the defaults. Useful if you’re dealing with ads that slip through on sites outside the mainstream English-language filter coverage.
Enterprise or managed devices sometimes have extension installation locked by IT policy. If the Add-ons store options are grayed out, that’s policy enforcement, not a bug on your end.
Prevention Tips
- Update your ad blocker’s filter lists regularly — most do this automatically, but check the extension’s settings if ads start slipping through
- Don’t install multiple overlapping ad-blocking extensions; one solid one is enough
- Only install extensions from the official Microsoft Edge Add-ons store
- Review extension permissions occasionally — an ad blocker needing access to “all websites” is normal, but check what else it’s requesting
FAQ
Do ad blockers actually make browsing faster, or does it just feel that way? It’s real. Blocking ad content means the browser skips downloading and rendering scripts, images, and video that would otherwise load. Less work, faster page paint.
Will an ad blocker break websites? Occasionally, yes — mostly sites with aggressive anti-adblock scripts or ones that inject content in a way the blocker misreads as an ad. Whitelisting fixes it instantly.
Is uBlock Origin better than AdBlock? For most people, yes, mainly because of the no-acceptable-ads-by-default approach and lower resource usage. AdBlock isn’t bad, just check its settings.
Does Tracking Prevention alone stop ads? Not fully. It reduces tracker-based ad targeting, not visible ad content itself.
Are Edge Add-ons store extensions safe? Generally, yes — they go through Microsoft’s review process. Sideloaded extensions from outside the store carry more risk.
Editor’s Opinion
honestly the built in tracking prevention thing is fine but people act like its the same as an ad blocker and it just isnt, i learned that the hard way expecting strict mode to clean up a page and it barely did anything visually. get a real extension, uBlock origin if you want the no nonsense option, and just whitelist the handful of sites you actually care about supporting. thats really the whole strategy
