Hello- I just refreshed my Firefox ESR version 52.2.1 (32-bit) Browser. Doing so removed all browser extensions. I am having trouble enabling (or installing, not sure which I need to do) the Online Security Extension. I cannot find the extension searching through Firefox add ons. Am I supposed to enable (or install) it through my Avast program? If so, how do I go about it?
Thank you very much
