eset password manager does not work anymore after last firefox update

I have Eset Smart Security Premium and had it's Passwordmanager installed in Firefox. This worked great until the update from Firefox about a month ago. Since then I cannot get it to work anymore. The Eset Passwordmanager icon disappeared and if I start the webpage with the Passwordmanager, it 'doesn't autofill the passwords anymore. Checking what the problem can be, I first saw that in firefocx add-ons the passwordmanager was moved to 'not supported' (in Dutch 'niet ondersteund&#039) with the discription (translated from Dutch, so it may be a little different): Outdated extensions These extensions do not meet current Firefox standards and are therefore deactivated. Eset password manager autofill engine could not be verified for use in firefox and is disabled.

After reinstalling Eset in an attempt to fix the problem, the problem is still the same, but also the message above is gone. I contacted Eset, but they could fix it eather. They say the problem has to do with Firefox and they would come back to it, but until today it is still not solved. So therefore I trying to get help from Firefox, hoping I don't have to switch to another browser. Can you help me?

Thanks in advance and kind regards, Marcel

Hi Marcel, do you have the very latest version of ESET? If you use the "More" link on an extension listing, it should provide access to the specific version number of the extension.

There is a difference between the Dutch FAQ and the English FAQ under Q3: the English one has this additional information:

Firefox x64: The 64-bit version of Firefox is not supported at this time.

Could you double-check that with support and see whether it could be the source of the problem?


You can manually install 32-bit Firefox by downloading a full installer from the following page. However, a couple precautions are in order:

Thank you very much for your answer. It makes a lot clear and I will contact support about this. Strange however that it did work for a while, until the firefox update.
