The new Netscape broswer, Netscape 8 is allegedly one of the securiest browsers around (it came out yesterday), definitely more secure than IE and maybe even better than Mozilla. However, as it turns out now, it has some serious security issues.
Netscape 8 was built on an early version of Mozilla Firefox which had some critical security problems. Mozilla's newest version of Mozilla Firefox doesn't have these problems anymore. However, Netscape on the other hand...do I need to say more?
