@AB, thanks for testing this as well! Out of curiosity, if you disable the AdBlock Plus extension in Chrome, are you able to open a website and fill it by choosing the matching Login? Also, are you using the same version of the AdBlock Plus extension as hawkmoth? I also have an AdBlock Plus extension installed in Chrome but it doesn't seem to be causing the same problem for me - although it looks like I'm using a different version than the one in hawkmoth's screenshot.
