8 days ago Firefox on my iPad lost my login and is asking me to log in again, but when I go to "enter your password to connect" I get a box with the message "could not load page" in red. The iPad is still linked to my account, I can see iPad bookmarks and open tabs on my Mac, and sync tabs etc. from my iPad on my Mac, but can't sync on the iPad. Firefox is showing version number as 14.0, and says the last update was yesterday. It's never done this before. Nothing has changed on my iPad as far as I'm aware, I haven't recently updated IOS, in fact my OS is a relatively old version because I don't usually upgrade unless I need to. I'd be grateful for any help.
