Reasons to use Firefox 3:
- It’s More Secure: Malware Protection, Secure add-on updates (though this will bar some legit ones like Neopets toolbar), Anti-virus integration & more
- It’s Easier to Use
- It’s More Personal
- It has Improved Performance: Speed, Memory Usage & Reliability have all been improved.
I’m running Firefox 3 right now, as it is much quicker going between pages than my Firefox 2 ever was. However not all my add-ons, which it automatically brings over with everything else when you install, do not work with Firefox 3. At least the important ones like AdBlock Plus and NoScript are amoung the ones that do work.
