I have been unable to use Last Pass for the past few months. I can't recall now at which Firefox update the Last Pass add-on ceased functioning properly, but I have been vacillating between using an alternative browser (usually Opera) with Last Pass and continuing to use Firefox, but with Bitwarden.

Bitwarden has been great; the only downside is that at present one cannot use it for Form Fills and to store Secure Notes, and such like. But it Autofills my passwords on Firefox with no problem at all.

I am a Last Pass paying subscriber but I am very likely to allow my subscription to lapse when it next becomes due.
