so far, Opera is the ONLY alternative browser to IE & Netscape that is attempting to do it all ...I am no expert on whether it does what YOU want, but there are LONG, detailed discussion forums about it, and someone there could no doubt answer your questions.

As to 'free'...it can be free, if you can tolerate a pretty small ad in one corner....otherwise, it is not expensive to eliminate that ad..(and of course, some even manage to get around that expense)
