Microsoft has a browser? Gosh, I learn something new every day.
I migrated from IE to Firefox long ago, but eventually moved to Chrome during a particularly bad time for Firefox when a series of bad releases had made it next to impossible to use. It's much better now, and I still use it when I want to bring up a second browser on a different screen.
There was also a great download manager for FF that I used to use for big downloads, until FF broke it. I should check if it works again, because it was very helpful for multi-gigabyte sample library downloads (faster, and could resume failed downloads).
