This is a better than "decentraleyes" since it is in active development. There are many more features in this compared to the other extension. I am finally making the move after using Decentraleyes for so long.
Firefox Sync is a great feature. Yes your fingerprints are tied to your firefox account but its better to have it than not have it.
