The problem with IE is not that its a bad browser, it's actually an OK browser, although I've been waiting for full PNG support in IE for ages, and it problably will never come at this rate. The main problem with IE is that it's integrated in your system. Active X are not a problem per say, nor are VB Script or Javascript. The problem is that once you find a way to exploit these technologies in IE, you can get complete access to an IE user's computer, and do some real damage. If IE was tied in the system so much, it wouldn't be a problem.
THAT's why Firefox, Mozilla, Opera or any non-IE browsers are more secure.
Aside from that, the reason I like Firefox so much:
- Extensions
- Extensions
- Extensions
!!!!
With the available extensions (and new ones are made every day) you can pretty much custom build the browser you want.
