Is Open site in removepaywall safe?

Open site in removepaywall sends the current tab's full URL to removepaywall.com when you click its menu item or toolbar icon.

The extension adds a context-menu item and toolbar button that open the page you are on through removepaywall.com's paywall-bypass service. On click, it opens a new tab to https://www.removepaywall.com/search?url= with your active tab's complete URL (including path and query string) appended, sending that URL to removepaywall.com. It runs no content scripts and requests only the contextMenus and activeTab permissions, so nothing is sent unless you trigger it.
