I've been hitting issues with site compatibility with Chrome lately, so I decided to start with a list of sites that I've had issues with in the last day, and I'll build on from there.
As of Chrome 39.0.2171.71 (64-bit) on Yosemite:
panel.dreamhost.com - Rebilling edit does not allow you to check the checkbox to limit billing on one day or specify an amount. (Only happened when my recurring was expired. Cannot reproduce now.)
Fidelity.com - Quicklinks dropdown after login collapses immediately instead of allowing you to select a menu item.
playstation.com - Password Reset password fields don't register that you're typing in any information (strength meter doesn't change), and when you submit, you password hasn't actually been changed. Same functionality worked in Firefox.
- GWT Developer Plugin installed but not recognized.
