I haven't heard that. I'm shocked anyone still uses internet explorer there are so many better ones.
Try chrome or firefox while you still can use internet explorer so that way you will be familiar with them. You won't go back. If you have any questions I'll help you out.
I understand that XP will be completely phased out support for Windows 7 is ending this month.<br />
I don't know if XP will still be usable or not.<br />
I use Firefox and Chrome, exclusively and removed IE.
I don't know but why mess with IE when there's Chrome and Firefox?
