It's a pain really Ummm. My laptop is the biggest pile of crap so I'm always reluctant to keep installing and removing stuff. I can put up with IE for now. Or maybe I should just be getting on with some work istead.
EvianBaby - if you prefer Firefox to IE and have a 64bit machine then you could give Waterfox http://waterfoxproject.org/downloads/ a go - that is still based on Firefox 11 (until the new version comes up next week).
There is also Pale Moon which is currently based on Firefox 11 but it uses a separate profile (unless you know the secret to using the FF profile).
