WARNING

Violentmonkey MV3 test build can be installed as an unpacked extension from our releases.

Brave doesn’t support Manifest V2 anymore — the MV2 code was removed from upstream Chromium by Google. If you use Brave and need to export your data, downgrade in place to v1.91.178 first to re-enable your extensions or use the MV3 test build and add "key" to its manifest.json as explained in the release.

Installation

Violentmonkey is built with web extension APIs, thus supports many browsers.
