I have a problem with KPM in Firefox. The KPM extension seems to be installed and enabled in Firefox 69.0.3 (64bit).
However, it does not seem to be working. As you cen see in the next picture, it is not in the list of extensions.
Simply, I cannot see a “key symbol” on any log-in page. I tried reinstalling Mozilla Firefoox and KPM. I use the latest versions of both. Does anybody experience the same issue. Thanks.
