Agent Browser Shield

Improve AI agent effectiveness.

** ALPHA RELEASE ** Free browser extension for making AI agent browser use more secure and effective: - Token efficiency: strip page chrome (footers, cookie banners, chat widgets, sponsored content) so agents spend tokens on the user's task. - Security & compliance: mask PII and credentials before they reach the model, and suppress hidden text, HTML comments, and user-generated content that could carry prompt-injection payloads. - Accuracy: block manipulative dark patterns and hide engagement rails and other content that could distract the model from the user's task. --- Documentation: https://pixiebrix.github.io/agent-browser-shield/ Source Available: https://github.com/pixiebrix/agent-browser-shield Bug Reports / Feature Requests: https://github.com/pixiebrix/agent-browser-shield/issues
