I primarily use Firefox, but we use Chrome at my college. Chrome CAN be nice, but it refuses to load pages FAR too often for me to use it regularly. About eight out of ten YouTube videos I try to watch I'll end up having to refresh the page five or six times to get the video to play. Some Google pages will load, then immediately go blank, causing me to refresh once or twice. Those are the main problem sites, but there are several others that do this on and off.
Granted, I haven't used too many scripts or add-ons for Chrome, so maybe somebody out there has fixed Chrome page loading with some third-party software, but I can't be arsed to look one up. :/
Got a million add-ons for Firefox though, and it works great, so I have no reason to switch.
