Is TabMark-Bookmark New Tab safe?

Low risk

TabMark-Bookmark New Tab renders your bookmark titles and URLs into every site you visit.

TabMark-Bookmark New Tab requests your browser bookmark tree on each page load and displays bookmark titles and URLs in a shadow DOM attached to the page. Because that shadow root is open, scripts running on the visited page can read the displayed bookmark links and titles.
