WARNING

Violentmonkey BETA is ManifestV3 now and after a test period will be published as stable. Meanwhile, you can re-enable your disabled stable version by downloading an MV3 zip from our releases and adding "key" to its manifest.json as explained in the release description.

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.
