Brave ships with its own ad and tracker blocker, so the obvious question is: why would you install uBlock Origin on top of it? For most people, you don’t have to. But there’s a specific group of power users who still benefit. Here’s the honest answer for 2026 — plus how to install uBO on Brave if you decide you want it.
Quick Answer
No, most Brave users do not need uBlock Origin. Brave’s built-in Shields already runs the same EasyList and EasyPrivacy filters that uBO uses, natively and with zero setup. Add uBlock Origin only if you want power-user tools Shields doesn’t fully match — the element zapper, network request logger, and per-site dynamic filtering. If you do install it, get it from Brave’s Manifest V2 extensions page so it keeps working.
Short answer: most Brave users don’t need uBlock Origin
Brave’s built-in Shields blocks ads and trackers natively using Brave’s open-source Rust engine. Crucially, that engine parses the same EasyList and EasyPrivacy filter syntax that uBlock Origin uses — so out of the box, Brave is already doing most of what uBO does, without an extension. It also applies cosmetic filters and injects uBlock-compatible scriptlets, which is why real-world blocking results between the two are close for everyday browsing.
For everyday browsing, Shields alone is enough. Adding uBlock Origin on top is redundant for the average user and can occasionally cause two blockers to fight over the same page. In fact, because both tools read the same lists, running them together doesn’t meaningfully block more ads — each request just gets checked twice, at a small CPU cost.
Brave Shields vs uBlock Origin: how they actually differ
The two tools overlap heavily on core ad blocking but diverge sharply once you look at privacy depth and hands-on control. Shields does things below the layer an extension can reach — like fingerprint randomization and ephemeral third-party storage partitioning — that no extension, including uBO, can replicate. uBlock Origin, meanwhile, wins on granular tooling: a request logger, a picker that can write network filters (not just hide elements with CSS), and a dynamic filtering matrix. Here’s how they stack up.
| Capability | Brave Shields | uBlock Origin |
|---|---|---|
| Ad & tracker blocking | Native, uses EasyList/EasyPrivacy | Uses the same EasyList/EasyPrivacy filters |
| Setup required | None — on by default | Install extension, then configure |
| Fingerprint randomization | Yes (extensions can’t do this) | No |
| Element zapper / picker | Basic “Block element” (CSS hide only) | Full picker that can write network filters |
| Network request logger | No | Yes — real-time request inspection |
| Per-site dynamic filtering | Simple per-site toggles | Granular rule matrix by domain & type |
| Custom filter lists | Supported, less transparent UI | Full control over lists & sources |
| Best for | Everyone — simple, robust default | Power users who want hands-on control |
The takeaway from the table: neither tool is strictly “better.” They optimize for different users. Shields is the stronger default for privacy and simplicity; uBO is the stronger toolkit if you like getting under the hood.
When uBlock Origin still adds something on Brave
uBlock Origin is worth installing on Brave if you’re a power user who wants tools Shields doesn’t fully replicate:
- The element zapper and element picker — click to remove any on-page element on the fly, and create your own cosmetic/network filters from it. Where Brave’s built-in “Block element” only hides things with CSS, uBO’s picker can write true network rules.
- The network request logger — inspect in real time exactly what’s being requested and blocked on a page, which is invaluable for troubleshooting a broken site or a sneaky tracker.
- Per-site dynamic filtering — uBO’s advanced matrix lets you block all third-party frames on one site, allow one domain’s scripts on another, and hard-block a tracker everywhere. Shields’ per-site toggles reach nothing this granular.
- Your own custom filter lists — if you maintain or subscribe to niche lists, uBO gives you fuller, more transparent control over them.
A common real-world example is a site with unusually stubborn ads that slip past default filters. If you’re chasing a specific case like that — say, blocking Twitch’s in-stream ads — uBO’s custom filters can do things Shields can’t. If none of those sound like you, stick with Shields.
How to install uBlock Origin on Brave
A key 2026 detail: uBlock Origin is a Manifest V2 extension, and Chromium has been phasing those out. Brave, however, continues to host a small set of MV2 extensions on its own backend specifically so they keep working. That list includes uBlock Origin, AdGuard, NoScript, and uMatrix.
To install it on the stable version of Brave:
- Open Brave and go to Settings → Extensions → Manifest V2 extensions.
- Enable/download uBlock Origin from there (Brave serves it through its own backend so it keeps functioning despite the broader MV2 deprecation).
- If prompted, allow the extension — some MV2 extensions also ask you to enable an “Allow User Scripts” toggle in their own options.
- Pin the uBO icon to your toolbar so you can reach the dashboard and picker quickly.
You can also install uBO from the Chrome Web Store on Brave, but using Brave’s own MV2 path is the more future-proof route.
Key Takeaways
- Brave Shields and uBlock Origin use the same EasyList/EasyPrivacy filters, so their everyday blocking is nearly identical.
- Shields adds privacy protections no extension can — like fingerprint randomization — while uBO adds power-user tooling.
- Running both doesn’t block more ads; it just double-checks each request and can cause hard-to-diagnose breakage.
- Install uBO from Brave’s Manifest V2 extensions page on the stable build for the most reliable, future-proof setup.
A note on Manifest V3 and Brave’s ongoing support
Because Shields is built into the browser rather than being an extension, it is completely unaffected by the Manifest V2-to-V3 transition — that’s the single biggest reason Shields is the safer long-term bet for most people. uBlock Origin’s full version, by contrast, depends on Brave (and Firefox) continuing to allow MV2 extensions.
Brave has publicly committed to keeping privacy-relevant MV2 extensions like uBO working “for as long as feasible.” That said, this support is being tested at the edges: a mid-2026 Brave beta build briefly disabled MV2 support, though the stable and Nightly channels were unaffected at the time. The practical guidance: if you rely on uBO, stay on the stable channel, keep an eye on Brave’s announcements, and remember that Shields remains a fully capable fallback if MV2 support ever ends.
Should you run Shields and uBlock Origin at the same time?
You can, but be deliberate about it. Running both fully overlapping is usually unnecessary and can cause:
- Double-blocking quirks — pages that break in ways that are hard to diagnose because two blockers are acting at once.
- Confusing troubleshooting — when something is blocked, you won’t know which tool did it.
- A small, needless CPU cost — every request gets evaluated twice against overlapping lists, for no extra ads blocked.
Two sensible approaches:
- Keep Shields as your main blocker and treat uBO as a power-user toolkit (zapper, logger) you reach for occasionally.
- Or lean on uBO for sites where you want its dynamic filtering, and relax Shields’ ad blocking on those specific sites to avoid conflicts.
Pick one as the primary engine rather than letting both go full force everywhere.
The bottom line
For the vast majority of Brave users, Brave Shields is all you need — it uses the same filter lists as uBlock Origin, adds privacy protections extensions can’t, and requires zero setup. Install uBlock Origin only if you want its advanced tools: the element zapper, network logger, dynamic filtering matrix, and custom lists. And if you do, get it through Brave’s Manifest V2 extensions page so it keeps working.
The Bottom Line
Use Brave Shields on its own and you’re covered — it blocks the same ads and trackers as uBlock Origin with none of the setup, plus fingerprint protection uBO can’t offer. Reach for uBlock Origin only when you want its hands-on control, and install it from Brave’s Manifest V2 page so it survives the Manifest V3 shift. For most people, one tool is the right answer, not two.
Frequently Asked Questions
Is uBlock Origin better than Brave Shields?
Not for everyday blocking — they use the same EasyList/EasyPrivacy filters, so results are nearly identical. uBO wins on advanced, hands-on control (the picker, logger, and dynamic filtering matrix); Shields wins on simplicity, zero setup, and privacy features like fingerprint randomization that no extension can match.
Does uBlock Origin still work on Brave in 2026?
Yes, on the stable channel. Brave hosts uBO (and a few other Manifest V2 extensions) on its own backend so it keeps functioning despite Chromium’s MV2 phase-out. Support is being tested at the margins, so it’s worth staying on the stable build and watching Brave’s announcements.
Do I need to turn off Brave Shields if I install uBlock Origin?
Not necessarily, but you should pick one as your primary blocker. Running both at full strength is redundant and can cause page-breakage that’s hard to trace. A common setup is keeping Shields on and using uBO occasionally for its tools, or leaning on uBO for specific sites while easing Shields there.
Will running both slow Brave down?
The performance hit is minor — mainly each request being checked twice against overlapping lists. The bigger downside is redundant blocking causing page issues that are annoying to debug. Designate one tool as your primary blocker to keep things clean.
Is Brave Shields enough for privacy on its own?
For most people, yes. Shields blocks ads and trackers, prevents cross-site cookies, and adds fingerprint randomization that extensions can’t replicate. Power users who want per-site request control or custom filter management are the main group who’ll benefit from adding uBlock Origin on top.
