Is Checkmarks safe?

Clean risk

This extension checks bookmarks for invalid entries by loading them and reporting request errors.

It batch-loads saved bookmarks in a configurable number of tabs so the browser can fetch favicons and detect loading problems. It shows a list of request errors for manual review, and it can optionally sort bookmarks and change bookmark titles to lowercase.
