I had an Amazon tablet stolen from me a couple weeks ago. A few days after it was stolen, I had Amazon lock the tablet, but I know that they had access at least to my Google and Amazon accounts which were logged in on the device. It only recently occurred to me that all of my passwords are saved in Firefox. Would they have been able to open Firefox and view all of my passwords? Would they have been able to go to websites and after the password auto filled, click show password? Are all of my passwords compromised? And do I need to start changing all of my passwords?
