# Brave Shields vs uBlock Origin 2026: 3 Reasons to Add It

> Does Brave Shields make uBlock Origin redundant? Mostly — it runs the same filter lists natively. The 3 tools uBlock still adds, as of July 2026.

> **Key takeaways**
> - Brave Shields runs **the same filter lists as uBlock Origin** through a native Rust engine, no extension required
> - uBlock Origin still adds **a temporary element zapper, a network logger, and per-site dynamic filtering** on top of Shields' built-in Block element
> - Brave hosts the **Manifest V2 version of uBlock Origin itself**, independent of the Chrome Web Store

Most Brave users do not need uBlock Origin. Brave Shields runs Brave's own Rust adblock engine natively, parses the same EasyList and EasyPrivacy syntax uBlock uses, and is untouched by Manifest V3. uBlock earns its spot in three cases: element removal beyond Shields' built-in Block element picker, the network logger, and per-site dynamic filtering.

## The Short Answer: Shields Already Does the Heavy Lifting

Shields is compiled into the browser: no extension API, no Web Store policy. The real comparison is tooling, not blocking power:

| Capability | Brave Shields (native) | uBlock Origin (extension) |
|---|---|---|
| Engine | adblock-rust (open source) | webRequest (MV2) |
| Filter syntax | EasyList / uBlock-compatible | EasyList and own lists |
| Cosmetic filtering | Yes, including procedural | Yes |
| Scriptlet injection | Yes, uBlock-compatible resources | Yes |
| Element picker / zapper | Block element (cosmetic only) | Yes, plus temporary zap |
| Network request logger | No | Yes |
| Per-site dynamic filtering | Basic per-site toggles | Full rule matrix |
| Fingerprint randomization | Yes | No |
| Survives MV2 removal | Not applicable (native) | On Brave: yes. On Chrome: no — disabled since Chrome 138 |

If nothing in the uBlock column made you nod, Shields covers you.

## What Brave Shields Blocks Without Any Extension

Shields ships on by default, fed by EasyList and EasyPrivacy plus Brave's own lists. The engine underneath, adblock-rust, is open source and handles network blocking, cosmetic filtering, procedural selectors, and scriptlet injection with uBlock-compatible resources. Custom filter lists go in `brave://settings/shields/filters`, and the right-click Block element picker writes per-site cosmetic rules to the same page.

Two Shields protections sit outside what any extension can do: fingerprint randomization and ephemeral third-party storage partitions. Both run below the layer extensions can reach.

## Three Cases Where uBlock Origin Earns Its Spot on Brave

**Element removal beyond CSS hiding.** A floating video player or sticky share bar that no filter list targets: Brave handles the basic case itself — right-click, Brave → Block element, and a picker with a specificity slider writes a permanent cosmetic rule. uBlock's picker goes two steps further: a zap mode that removes an element for this visit only, no rule saved, and network filters that stop the resource downloading instead of just hiding it.

**Inspecting what gets blocked.** uBlock's logger shows every request a page makes and which filter caught it. If you debug broken pages or audit what sites load, this alone justifies the install.

**Per-site dynamic filtering.** uBlock's rule matrix can 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.

## The MV2 Question: Why Brave Is the Safer Home for uBlock Origin

Chrome disabled Manifest V2 extensions in Chrome 138 (July 2025), then removed the enterprise escape hatch at Chrome 139. Full uBlock Origin has not run on stable Chrome since. Its Chrome Web Store listing was never taken down — v1.72.2, updated July 2026, is still there — but installing it does nothing, and Google removes all remaining MV2 extensions from the store on August 31, 2026; [does uBlock Origin still work on Chrome](/library/does-ublock-origin-still-work-chrome-2026/) tracks the full status.

Brave went the other way: it hosts four MV2 extensions on its own backend (uBlock Origin, AdGuard, NoScript, uMatrix), installable from `brave://settings/extensions/v2`. Support is best-effort, but the dependency is Brave's stated commitment rather than Google's tolerance. For a complete picture of what the MV2-to-MV3 transition actually restricted — declarativeNetRequest rule caps, the loss of blocking webRequest, and what ad blockers had to rebuild — [Manifest V2 vs V3 explained](/library/chrome-manifest-v2-vs-v3-extensions/) is the place to start.

## Running Both, and What Chrome Users Should Do Instead

Running both checks every request twice against largely identical lists: a small CPU cost for uBlock's tooling. If a page breaks, toggle one layer off to find the culprit.

Chrome has no Shields layer, so an ad blocker carries the full load and [pairs well with tab suspension](/library/tab-suspender-vs-chrome-memory-saver/) on the memory side. SuperchargePerformance does both: `declarativeNetRequest` ad and tracker blocking plus `chrome.tabs.discard()` suspension, 100% local, no account.

Where you land:

- **On Brave and never opened a filter list in your life** → Shields alone. Done.
- **On Brave and you audit requests or write per-site rules** → add uBlock Origin from `brave://settings/extensions/v2`.
- **On Chrome and staying** → full uBlock Origin no longer runs there; use uBlock Origin Lite, or SuperchargePerformance for blocking plus memory management.
- **Choosing a browser on RAM, not blocking** → see [which browser uses the least RAM](/library/which-browser-uses-least-ram-2026/) and the [Brave vs Chrome RAM breakdown](/library/brave-vs-chrome-ram-benchmark-2026/).
