Is Local Filesystem Links safe?

Clean risk

Local Filesystem Links sends clicked file:// URLs from web pages to its native helper app.

Local Filesystem Links injects a content script into matching active tabs and attaches click handlers to file:// links. When a user clicks one of those links, it sends the decoded file URL and open/reveal options to the local native messaging host so the helper can open the file or folder.
