    is there a point to this?why not stick to Maxthon? everything you'll ever need in 1 browser?

    Lately Firefox is very disappointing. New Betas every other day, not as stable and Fun as it used to be. I wish I could use Opera on everything, but in its place it's Chrome. This is IE engine not FF

    don't know about other OS but i'm on Win 7 and though it shows google toolbar it wont let u sign in to get ur google i don't rate it...anyway its based on internet explorer so if u want to go with ie then do so with chrome frame enabled..not bad at all!
