I want to switch from Microsoft IE to either Firefox, Chrome, Opera, or Safari, especially because of this big new Microsoft IE flaw, but I'm worried I'll lose files. If I make the switch to a new browser, will I lose my favorites folder or my e-mails? Also, can I switch back at any time in the future if I'm unhappy with whatever browser I end up choosing? I know very little about computers and before I do something, I want to make sure I'm not going to regret it. Thanks in advance. :)
