Could someone please explain to me the major differences between Mozilla 1.4 and Mozilla Firebird? I’d like to try one of them but the Mozilla website does not really make it clear how they differ. Am I correct in assuming that Firebird is just a bare bones version of 1.4?
What should I be aware of before choosing one of these? Also, I have not really looked into the Opera browser at all. Should I be considering it as a canditate? Are there any important features in IE which I would lose by choosing any of the above?
And last, given the many security vulnerabilities present in Outlook Express (as Gabe Newell recently found out), I am interested in other E-mail applications. Do any of the alternatives out there present a more secure option?
Aside from security issues, I have been satisfied with both IE and OE.
Any opinions/comparisons would be welcome.
