Hello @Nassim Mezlini and @RenéM,
we have build 18.104.22.168 of the ESET Password Manager ready, which supports the current Firefox version.
Currently it is available for the pre-release users and should be available for general public in the following days.
So in case you would like to get it right now, please switch your update type to pre-release.
