I have downloaded Mozilla Thunderbird and Firefox, is it safe to delete internet explorer and Outlook Express?
Don’t delete IE (i am not sure you can, anyway) I am a dedicated Firefox user, but you will find one or two sites which require IE – so it is a good idea to keep as a backup… there is not problem having them both, in fact you can even run both at the same time (I’ve had to do that once or twice for testing purposes at work) you can remove Outlook.
