Traffic Light not secure - why not make it secure?

Today, after many years, I uninstalled Traffic Light.  The reason is because I discovered that every website a user browses to will be transmitted to your company in plain text.  As you likely know, quite a few other browser extensions apparently do the same, but that certainly does not make it right.  I was certainly under the understanding that Traffic Light was secure, but apparently not.

Why would you not have fixed this issue?
