Have used 3 browsers on our Windows 7 Pro X64 laptops:
 IE (the absolute worst);
 Google Chrome (which attempts to install crap onto your system you neither want or need);
 Firefox (which Zone Alarm Security classifies as "malicious.")
I will open up a can of worms with this question; I already regret it.
Six people will have 6 different opinions.
If there is such a creature, what is the "best," most useful browser available?
PS: I apologize.
