I started using Firefox because I literally coudn't use Chrome anymore on my PC. Every time I opened Chrome it would hard lock and I needed to ctrl-alt-del, end-task. Even re-installing and clearing out cache and folders didn't help. I haven't been able to open Chrome for months. Using Firefox for 1 week was a bit of usability shock. But it's so awesome once you get used to it. Everything is indeed so much more thoughtful. Every feature.
