I just noticed that mytrezor.com stopped working for me (Firefox on Lubuntu 14.04) as i get the message "Transport loading failed".
The log says "Failed to load Chrome Extension transport", does this mean that i cant use mytrezor with Firefox anymore?

Also i never updated my firmeware as i was afraid to loose my BTC because of some error, was there any reported problem caused by updating the firmeware in Trezors lifetime?
