The extension GREATLY slow-down whole firefox (tested with profiler, and official Gecko Debugger) on FF61, 62, 63 (nightly). Can't recommend, because it's slowdown page loading super very much. And without the extension overall browser performance greatly increased. Fix perfroamance issues first before releasing this addon.

this add on is so disorganized and so difficult to install, after installation it forced me to register, which I did not want, received no feed back and no indication I could use it, then kept on pushing me to install the MS APP version, additional to the non existent feed back forced me to remove the add on.

Trying to add to Firefox and keeps saying cannot due to a connection issue. I am connected to the web.

Stopped working a month back. Reinstalling didn't help.

It's not working like it should. It doesn't let me login so I can use any of the features.

id like to give it azero becouze it keeps telling me it is courupted
