Hello,

I am currently using Kaspersky Internet Security 2019 on both computers, and on mine it updated to the 2020 version, and I went to the Kaspersky forum and asked how do I re-install the 2019 version and I was given the help, however, now I have lost the Kaspersky Protection 2019 Add-On on Firefox, and when I look to see about installing the Kaspersky, it isn't listed on Firefox anymore.

Where can I find the 2019 Add-On?

Thank you,
