Is PDF Bookmark safe?

Low risk

PDF Bookmark scans page HTML for a hardcoded keyword and stores matching page URLs with match counts in memory.

PDF Bookmark runs a content script on every site and counts matches for a hardcoded keyword in the page HTML. When it finds matches, it sends the current page URL and match count to the background worker, which stores the count in memory for that URL.
