FF has all that I need. Switched to it after the worm Bugbear crashed failing to infect my PC and I discovered that I risked having my personal data, including credit card number and passwords, stolen, because that pile of dung of IE, despite I explicity chose in its settings to not memorize those data, silently stored it in the infamous index.dat (and it kept on doing it for years, BTW).
Now I use IE only to access Windows Update.
