Just updated to latest Firefox version 62.0 and it disabled the Trend Micro toolbar. I expect you will be hearing from others about this breakage and incompatibility. I am assuming this means my Trend Micro is not protecting me when I am web browsing... ? ? ?
Customers should understand that TMTS and the extension are separate programs, and breaks like this are going to be more common as the means to hack a person or organization's computers become more complex and severe.
Browser and OS Updates are necessary and sometimes these things happen. Given this only occurred a week ago, I'd say TM's response time is more than acceptable.
