Can't get Linux Chrome to load the plugin. I'll investigate that later. Works fine in Firefox.
Google dropped native plugin support in Chrome 35 on Linux. 6 months ahead of their original schedule. :-/
We already have a replacement which is in final phase of testing and we will rolling be that out soon.
(New TREZOR Bridge will start a local micro webserver so myTREZOR can connect to it and communicate with TREZOR).
