NOTE

This extension does not contain any ads and does not modify web pages automatically. Any changes and modifications on the sites are done by installed scripts. Therefore, please install only scripts that you trust.

WARNING

This extension is no longer supported on Chrome due to its Manifest V2 architecture. While a Manifest V3 rewrite might be considered in the future, it is not planned for the foreseeable future due to the considerable effort involved and the potential for losing existing features.

Brave has also lost Manifest V2 support — 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.

Installation

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