Opera starts up faster than Firefox, but it loads pages slower
than Firefox.
The only beauty for Opera is the indicator that it's loading
pages. So you can stare at that indicator and count how many
pictures before it finishes loading.
Firefox will still be my main one, followed by Opera. Safari
search function seriously suck. And adds one redundant service to
Windows. Plus, the amount of temp files created is more than the
temp files created by IE. Now you know why Safari is able to load
pages up faster.
I always thought IE is a good way to waste your HDD space, here
comes a better one that wastes even more space.
