User reviews
I used to love this extension. It was BY FAR the best solution for using multiple browsers to sync over all devices. In the last six months or so, it has quit working as well. Now, it is impossible to organize because it keeps re-syncing and overwriting changes made on the browser. In my Linux installations, I now get an error message for which the meaning is impossible to track down and it doesn't sync at all.
