Goooooogle Rated 5 out of 5 stars
It seems that Google is playing cat and mouse with you guys (and the other similar addon). 1.0.3 no longer works since an hour or so.This review is for a previous version of the add-on (188.8.131.52-signed).
Thanks for letting me know! They changed all the IDs again...
Edit: Bugfix version 1.0.4 is out. (Unfortunately this reset my place in the review queue...)
