Lockwise does not work.

Hello

I wish I could use your addon, because the idea behind it sounds great. Unfortunately, I can’t, because it does not work at all (desktop version, the iOS version seems to work without any problems).

Whenever I click either on „manage passwords“ in the Firefox options or on that new key in the right corner and „open lockwise“, all I get is a blank, white screen. I deleted and reinstalled it, but it didn’t do anything.
I deactivated all addons, except lockwise off course, and tried it that way, but it didn’t do anything either. I have no idea what I did wrong…

Firefox is the newest version (67.0.1) and my operating system is windows 10 home.

Any help would be much appreciated.

Kind regards, Stefan
