I'm a user of Firefox 5 and am having intermittent browser stalls. I haven't seen what it means that ZA 10 "doesn't support Firefox 5" but the ZA help desk thought ZA 10 might be the problem so they gave me instructions for uninstalling 10 and reinstalling 9. They didn't say if it could all be done offline. Can it? (I know I have to be online to reregister. I'm asking only about the uninstall/reinstall process.)
