Google Chrome is obviously the best, but not without its problems. One I just had was with the last update. For some reason when I had multiple tabs opened, it was an issue switching back to another tab. It would appear to stay at the last one I had clicked. But, here's a fix.
1. Open Chrome
2. Go to chrome://plugins/
3. Expand the details
4. Disable PepperFlash
