Features

• Live stream playback protection
• VOD pre-roll handling (when a clean source is available)
• Display / overlay cleanup
• Narrow network rules for known ad hosts
• Multiple protection layers
• Local statistics (stored in your browser only)
• No telemetry
• Open source
• Chrome, Brave, Edge, and Firefox (Manifest V3)

Installation

Recommended: download a release

Normal users do not need Node.js or npm.

1. Open the Releases page.
2. Download the latest KickBlock-vX.X.X.zip.
3. Extract the ZIP to a normal folder on your computer.
4. Open your browser’s extensions page:
   • Chrome → chrome://extensions
   • Edge → edge://extensions
   • Brave → brave://extensions
5. Enable Developer mode.
6. Click Load unpacked.
7. Select the extracted folder that contains manifest.json
   (for example KickBlock-v2.0.0/ — not the ZIP itself, and not a parent folder).
8. Open Kick and check that KickBlock shows as active in the popup.

Firefox (temporary load):

1. Open about:debugging#/runtime/this-firefox
2. Click Load Temporary Add-on…
3. Select manifest.json inside the extracted folder

Tip: if you use another Kick ad blocker at the same time, disable it while testing KickBlock. Multiple Worker hooks can conflict.

Extension popup

The popup shows protection status, local block counts, the current Kick page, active layers, and a shortcut to settings. Numbers in screenshots are UI examples.

Settings

You can control:

• Master protection
• Player protection (live + VOD)
• Display cleanup
• Ad tracker blocking
• Badge counter
• Debug mode and local statistics

How it works

Kick serves different ad types differently. KickBlock uses several layers and only changes what it can verify safely.

Cleaner playback (when safe)

If a technique is uncertain, KickBlock fails open: normal playback continues instead of breaking the player.

Live streams

Live ads are often server-side ad insertion inside Kick’s IVS player path. KickBlock installs an early MAIN-world hook, wraps the player worker when needed, and swaps stitched HLS masters for Kick’s public channel playback_url when that path is available.

VOD

VOD ads are usually stitched into the playlist (MediaTailor / manifest), not separate Google IMA creatives. KickBlock rewrites the playback API response:

1. Match /api/v*/stream/<uuid>/playback (absolute or relative)
2. Detect stitched / MediaTailor / production-kick-vod / manifest.m3u8 sources
3. Prefer a clean HLS source from the channel videos API (UUID first, then duration/title)
4. Replace playback_url.vod and clear vod_session / MediaTailor session fields
5. If no clean source is found, leave playback alone

Live vs VOD

Privacy

• Runs locally in your browser
• Statistics stay on your device
• Does not send browsing activity or usage stats to a remote analytics service
• No accounts required

Permissions

Permission	Why
storage	Settings and local stats
activeTab	Show the current page label in the popup
declarativeNetRequest	Narrow rules for known ad hosts
https://kick.com/*	Content scripts and Kick APIs used for clean VOD sources

Limitations

• Kick can change its player and ad infrastructure at any time
• Some server-side inserted advertising may not be separable from content
• Older VODs may not expose enough data for a safe source swap
• Browser behavior can differ
• When detection is uncertain, KickBlock intentionally fails open

Troubleshooting

Extension does not appear active

• Refresh Kick
• Open the KickBlock popup and confirm protection is on
• If you loaded an unpacked build, reload the extension from the browser extensions page

Player stops or behaves strangely

• Disable KickBlock temporarily
• Refresh the page
• Open an issue with browser, Kick page type (live/VOD), and version

Release installation does not work

• Enable Developer mode
• Point Load unpacked at the folder that contains manifest.json
• Do not select the ZIP file itself
• Re-download the latest release if the extract looks incomplete

Development

git clone https://github.com/NullEx17/KickBlock.git
cd KickBlock
npm install
npm run build

Load the dist/ folder with Load unpacked.

npm run typecheck
npm run lint
npm run test
npm run build
npm run package

npm run package builds the extension and writes release/KickBlock-vX.X.X.zip.

See CONTRIBUTING.md.

dist/ is build output and is not committed. Releases ship a packaged ZIP built from dist/.
