* feat: revert Kimi partnership UI, restore daily limit survey

Remove Kimi/Moonshot AI partnership branding from the rate limit
banner, provider card, provider templates, and LLM hub. Restore
the original survey CTA on daily limit errors. Moonshot AI remains
as a regular provider template without the "Recommended" badge.

* fix: address Greptile review comments

- Guard survey CTA with !isCreditsExhausted to avoid showing it for
  credits-exhausted users who already see "View Usage & Billing"
- Remove dead kimi-launch feature flag files (kimi-launch.ts,
  useKimiLaunch.ts)
- Remove unused KIMI_RATE_LIMIT analytics events
- Remove VITE_PUBLIC_KIMI_LAUNCH from env schema and .env.example

title: "Ad Blocking"
description: "BrowserOS supports full ad blocking with uBlock Origin"
---
BrowserOS supports full ad blocking through [uBlock Origin](https://ublockorigin.com/), the most powerful open-source ad blocker available — the full extension, not the watered-down "Lite" version.
## Why BrowserOS?
Chrome [killed support](https://developer.chrome.com/docs/extensions/develop/migrate/mv2-deprecation-timeline) for uBlock Origin by phasing out Manifest V2 extensions. The only option left on Chrome is "uBlock Origin Lite," a significantly weaker version that can't use advanced filtering rules.
**BrowserOS re-enabled full Manifest V2 support**, so you can install and run the original uBlock Origin at full power — the same extension Chrome no longer allows.
<Card title="Install uBlock Origin" icon="shield-check" href="https://chromewebstore.google.com/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm">
Install the full uBlock Origin extension from the Chrome Web Store. Works on BrowserOS out of the box.

## BrowserOS vs Chrome
We ran both browsers through [adblock.turtlecute.org](https://adblock.turtlecute.org/), a test that measures how effectively a browser blocks ads and tracking scripts.

<Card title="BrowserOS — 68%">
<img src="/images/adblock-browseros.png" alt="BrowserOS blocking 68% of ads" />
</Card>
<Card title="Chrome — 7%">
<img src="/images/adblock-chrome.png" alt="Chrome blocking only 7% of ads" />
</Card>
</CardGroup>
Out of 133 ad-related requests:
- **BrowserOS** blocked 91 (68%)
- **Chrome** blocked 9 (7%)
That's roughly **10x more protection** with zero configuration.
## What This Means
Fewer ads means faster page loads, less bandwidth usage, and significantly reduced tracking. BrowserOS handles this natively so you can focus on browsing.
