MyTrezor.com doesn't work on Chrome anymore (because of Google - not Trezor). But it still does on Firefox.
It does now!
Chrome turns off NPAPI plugins, which sucks; on the other hand, they have a great USB HID API for Chrome apps, which makes up for it and which we used.
How can you have Failed to load Chrome ... on Firefox?
See my previous post. That's a log message that we print even when we are on Firefox, since we try the Chrome extension first.
