Plug-in fails since last FF upgrade (55.0.2)

Just upgraded Firefox yesterday to 55.0.2 on Windows.

Enpass plugin no longer works since then.

Symptom : when clicking on the Enpass button, a brief window is opening in Firefox (disappearing quickly), reporting a "Access Denied! Error 403" message (see attached snapshot).

Any idea how to recover the Enpass plugin ?

Thanks

I was contacted by support.

=> suggestion : re-install Firefox

And it works...

Strange, but good to know !
