Is GrabzIt Web Scraping Assistant safe?

Low risk

GrabzIt Assistant strips security headers and reroutes scripts on grabz.it scrape tabs, and the rules persist after navigation.

The extension supports the grabz.it web scraping service. For tabs opened on grabz.it scrape pages, it removes Content-Security-Policy, X-Frame-Options and CORS headers from subframes, removes Referer and Origin headers, and redirects subframe script requests through grabz.it's proxy. These listeners are not removed when the tab navigates to another site, so they stay active on whatever site that tab loads next.
