I used to really like Moz's toolbar and metrics, but since the beginning of this year, both their Chrome toolbar and their metrics have been, for lack of a better term, "broken". I'm going to be lazy and just quote myself here:
Since around January of 2016, the Moz toolbar has been broken. Despite all of the complaints, Moz has yet to fix the ongoing issues surrounding its plugin including, but not limited to:
Metrics not being displayed
Graphical glitches
The toolbar interfering with page elements on certain websites
Issues surrounding logging in to use the metrics, only to discover that the toolbar doesn’t detect that you’re logged in.
As for the metrics, while I understand that these 3rd party metrics are meant to be estimations of a site's ranking potential, Moz's metrics seem to have a problem that Ahrefs doesn't. I'm not sure what causes it specifically, but I've noticed that every site I switch to HTTPS on ostensibly loses their PA and DA (if I recall correctly, Moz wasn't even picking up 5% of the backlinks of the sites I checked anytime after the switch). This didn't happen with Ahrefs, so I switched to their toolbar immediately after.
Anyway, it's unfortunate that those workers got laid off.
