Hi, I cannot get Mcafee Webadvisor to install and work on Firefox 84.0. Besides the obvious, I have deleted/uninstalled Webadvisor, uninstalled Firefox, deleted all Mozilla directories in Roaming, Local, LocalLow, Program Files, Program Files (X86) and Program Data, rebooted, reinstalled Firefox, reinstalled webadvisor both with Firefox opened. When that did not work, I then did all that again and tried reinstalling webadvisor with Firefox closed. Webadvisor does not appear in the Extensions lists. I can install other addons such as Ad Blocker Plus (ABP) via Firefox with no problems. I am running three laptops all with Firefox 84.0 and only one of them is having this problem.

Thanks for any help.


I am using W10 Home on a 2-year old Dell Inspiron with 8M DRAM, Intel i5 MCU.
