## Description

Quiet Blocker is a private alternative to the big ad blockers for Firefox. It blocks ads and trackers using the well-known community filter lists, and it does nothing else: no telemetry, no account, and no “acceptable ads” programme that lets paying advertisers through. It is free.

### Privacy first

- **No telemetry.** It sends no usage data, statistics or crash reports, and it never contacts a server of its own.

- **No account and no “acceptable ads”.** Everything the filter lists cover is blocked.

- **The only network traffic is filter-list downloads,** straight from the list maintainers (easylist.to, fanboy.co.nz, pgl.yoyo.org), sent with no cookies and no referrer.

- **Your settings stay in your Firefox profile** on your computer. Nothing is synced or uploaded.

### What it blocks

- **Ad and tracker requests** before they load: scripts, images, frames, tracking pixels, beacons, websockets and more.

- **Ad elements on the page,** using the lists' hiding rules, including ads that appear after the page has loaded.

- **Empty boxes** that blocked ad images, videos and frames would otherwise leave behind.

- **YouTube ads:** it removes the ad data from YouTube's player responses, so pre-roll and mid-roll ads don't play.

- **Adblock Plus / EasyList filter syntax:** domain blocks, exceptions (@@), type and domain options, element hiding (##) and page-level exceptions.

### Fast

In the developer's own test tool, about 150,000 filters load in roughly 0.2 seconds, and checking one request takes about 13 microseconds. Your numbers depend on your computer.

### Filter lists

Filter lists are rule sets maintained by volunteers. Quiet Blocker downloads them from their maintainers; it is not affiliated with or endorsed by them.

| List | What it blocks | On by default |
| --- | --- | --- |
| EasyList (EasyList authors) | Ads | Yes |
| EasyPrivacy (EasyList authors) | Trackers and analytics | Yes |
| Peter Lowe's list | Ad and tracking servers | Yes |
| Fanboy's Social | Social media buttons and trackers | Yes |
| Fanboy's Annoyances | Pop-ups, newsletter boxes, chat widgets | No |
| EasyList Cookie | Cookie consent banners | No |

Lists update automatically every 4 days; if a download fails, it tries again every hour. You can add any other list in Adblock Plus format by its https:// address.

### Tracking tag removal

Many links carry tags that tell a site where you came from. Quiet Blocker removes them from the address of pages you open: everything starting with utm_, plus fbclid, gclid, msclkid and about twenty others. The rest of the address stays exactly as it was: ?utm_source=news&id=5&fbclid=abc#top becomes ?id=5#top. You can turn this off in Settings.

### Hide this element

If an ad slips through, right-click it and choose **Hide this element**. A preview highlights what will be hidden; **Bigger** and **Smaller** change the selection, **Hide** confirms and **Cancel** (or Esc) closes the preview. The element stays hidden on later visits to that site, and the rule is saved under *My filters*, where you can edit or delete it.

## Frequently Asked Questions

**Q: Is it really free?**
A: Yes. There is no paid version, no subscription and no “acceptable ads” deal.

**Q: Why do you ask for my email and location?**
A: To send you the download link and to count downloads by country, in total. Release notes are sent only if you tick the box, and we never sell your details; see our privacy policy.

**Q: Does it collect my browsing data?**
A: No. It has no telemetry and never contacts a server of its own; its only traffic is downloading the filter lists, without cookies or a referrer.

**Q: Is it safe to install a file from this site?**
A: The add-on is signed by Mozilla, which Firefox checks before it installs anything. Firefox refuses a file whose signature does not match.

**Q: How do I get new versions?**
A: From version 1.2.0, Firefox updates Quiet Blocker by itself; that check sends no personal data beyond what any web request carries. If you have an older version, install the current one from this page once.

**Q: Will it work with my other ad blocker?**
A: Run one blocker at a time. Two blockers do the same work twice and can break sites.

**Q: What doesn't it do?**
A: It runs in desktop Firefox only: there is no Chrome, Edge or Safari version. Rules only uBlock Origin understands (scriptlets, $redirect and similar, about 0.3% of EasyList) are skipped, and when YouTube changes how it delivers ads, an update may be needed.

**Q: How do I uninstall it?**
A: Firefox menu → Add-ons and themes → Quiet Blocker → … → Remove. Save a backup first if you want to keep your filters and settings.
