mytrezor website is unusable. It freezes and few moments later browser tells me that trezor plugin is not responding. I can't even click on the "Support" link. Both firefox and chrome act the same way. Both trezor plugged in and plugged out.
I've had this problem, too. Can't click support link unless the plugin is working (which can't because my chrome is too new). The popup telling me to dl the plugin is modal and blocking everything else it seems. Can't be closed either.
