Clicking https://www.facebook.com/humansatsea/posts/1830041430363916 goes to http://www.themaritimepost.com/terrifying-footage-shows-board-ship-north-sea-storm/ and the page didn’t load in new tab. Tried to reload and blank tab. I flicked out to chrome with the link and it loaded fine.
Started writing this then to get the URL’s I jumped into (Brave browser) Facebook and tried to click again and it worked.
Many thanks to everyone bringing this to be (& for the clear posting instructions here too!)
Brave is fabulous
