Is 404 Bookmarks safe?
404 Bookmarks opens each saved bookmark URL to check whether it returns a 404 response.
When you open its page, the extension enumerates browser bookmarks and fetches each web URL, skipping only non-web schemes, to inspect the HTTP status and page body for 404 text. Those requests go to the bookmarked sites, which can reveal your IP address and that the bookmark exists to each site contacted.
AI-generated. Findings may contain errors. Those marked Verified have been manually reviewed.
