But as for things I really LIKE about this firefox update, I love the fact that now, when it can't open a page due to lack of connection, it sends you to that "Server not found" page, rather than the old method of just having a "Server not found" message box and not preserving the URL you were trying to access, thus possibly giving you absolutely no idea of what page you were trying to load if you're doing a whole lot of tabbed browsing.

WOO!
