The text says “Update bookmark “IEs 4 Linux – Internet Explorers for Linux – English Page”? The page has moved to the location http://www.tatanka.com.br/ies4linux/index-en.html. [Don't update] [Update].
When a web site is moved to a new address, it can use several ways to redirect visitors to the new address. If it’s a permanent move, the correct way is to send a HTTP 301 Moved Permanently. As it turns out, Epiphany notices such redirects and offers to update your bookmark, if you have bookmarked the site’s old location.
I’m impressed. The developers of Epiphany really did their homework here.
