Worked beautifully just a week ago, but after FF update, no longer works. At all. Also doesn't work on Opera or Chrome. Not sure whether it's the FF update or if there's some kind of bait and switch going on. Just two weeks ago one wasn't *required* to sign privacy and usage agreements. Looks like they initially offered their service for free, to grease the wheels, and are now trying to push users into privacy/usage agreements that allow them to collect usage patterns and expand their add-on as a synchronized service across multiple devices and platforms (except, apparently, Android). A cool service in theory, but in practice it looks as if they've somehow mucked this all up. in my own case, I didn't sign the agreement, and now can't access anything. Especially don't like the *not-optional* agreement that gives them to right to, you guessed it, turn you once again into the product... Am removing the add-on for now. Will check in during the next weeks to see what kind of product they want to be.
